+=== YANG Identifiers Mapping
+
+Every non-Java char in identifier is converted to Java char by its unicode name http://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.8
+JAVA SE SPECIFICATIONS - Identifiers. This mapping solves various issues from Binding Specification v1, which led to compilation issues.
+
+There are special types of mapping non-java chars to original identifiers according to specific Java type:
+
+* class, enum, interface
+
+** without special separator
+the first character of identifier, any other first character of identifier part mapped by
+** non-Java char name from unicode and char in identifier behind non-java char name are converting to upper case
+
+ examples:
+ example* - ExampleAsterisk
+ example*example - ExampleAserisksExample
+ \example - ReverseSolidusExample
+ 1example - DigitOneExample
+ example1 - Example1
+ int - IntReservedKeyword
+ con - ConReservedKeyword
+
+* enum value, constant
+** used underscore as special separator
+** converted identifier to upper case
+
+ examples:
+ example* - EXAMPLE_ASTERISK
+ example*example - EXAMPLE_ASTERISK_EXAMPLE
+ \example - REVERSE_SOLIDUS_EXAMPLE
+ 1example - DIGIT_ONE_EXAMPLE
+ example1 - EXAMPLE1
+ int - INT_RESERVED_KEYWORD
+ con - CON_RESERVED_KEYWORD
+
+* method, variable
+** without special separator
+** the first character of identifier is converting to lower case
+** any other first character of identifier part mapped by non-Java char name from unicode and char in identifier behind non-java char name are converting to upper case
+
+ examples:
+ example* - exampleAsterisk
+ example*example - exampleAserisksExample
+ \example - reverseSolidusExample
+ 1example - digitOneExample
+ example1 - example1
+ int - intReservedKeyword
+ con - conReservedKeyword
+
+* package - full package name - https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html
+** parts of package name are separated by dots
+** parts of package name are converting to lower case
+** if parts of package name are reserved Java or Windows keywords, such as 'int' the suggested convention is to add an underscore to keyword
+** dash is parsed as underscore according to https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html
+
+ examples:
+ org.example* - org.exampleasterisk
+ org.example*example - org.exampleasteriskexample
+ org.example - org.reversesolidusexample
+ org.1example - org.digitoneexample
+ org.example1 - org.example1
+ org.int - org.int_
+ org.con - org.con_
+ org.foo-cont - org.foo_cont
+
+==== Special case - '-' in identifiers
+There is special case in CLASS, INTERFACE, ENUM, ENUM VALUE, CONSTANT, METHOD and VARIABLE if
+identifier contains single dash - then the converter ignores the single dash in the way of the
+non-java chars. In other way, if dash is the first or the last char in the identifier or there is
+more dashes in a row in the identifier, then these dashes are converted as non-java chars.
+
+Example:
+
+* class, enum, interface
+
+ foo-cont - FooCont
+ foo--cont - FooHyphenMinusHyphenMinusCont
+ -foo - HyphenMinusFoo
+ foo- - FooHyphenMinus
+
+* enum value, constant
+
+ foo-cont - FOO_CONT
+ foo--cont - FOO_HYPHEN_MINUS_HYPHEN_MINUS_CONT
+ -foo - HYPHEN_MINUS_FOO
+ foo- - FOO_HYPHEN_MINUS
+
+* method, variable
+
+ foo-cont - fooCont
+ foo--cont - fooHyphenMinusHyphenMinusCont
+ -foo - hyphenMinusFoo
+ foo- - fooHyphenMinus
+
+==== Special case - same class (or enum or interface) names with different camel cases
+Next special case talks about normalizing class name which already exists in package - but with
+different camel cases (foo, Foo, fOo, ...). To every next classes with same names will by added
+their actual rank (serial number), except the first one. This working for CLASS, ENUM and
+INTEFACE java identifiers. If there exist the same ENUM VALUES in ENUM (with different camel
+cases), then it's parsed with same logic like CLASSES, ENUMS and INTERFACES but according to list
+of pairs of their ENUM parent. Example:
+
+* class, enum, interface
+
+ package name org.example, class (or interface or enum) Foo - normalized to Foo
+ package name org.example, class (or interface or enum) fOo - normalized to Foo1
+
+* enum value
+
+ type enumeration {
+ enum foo;
+ enum Foo;
+ }
+ YANG enum values will be mapped to 'FOO' and 'FOO_1' Java enum values.

=== Binding Specification v2 Concepts
-<<Instantiated>>::
- Represent node, which is instantiated
+<<Instantiable>>::
+ Represent node, which is instantiable by users as a part of notification,
+ rpc, action or data tree.
<<TreeNode>>::
Represents node, which is part of instantiated data tree, this interface
is not used directly, but rather via <<TreeChildNode>>. See <<instantiated-data-tree-rules>>
for more information.
<<TreeRoot>>::
- Represents virtual root of instantiated data tree node.
+ Represents virtual root of instantiated data tree.
<<TreeChildNode>>::
Represents node, which is part of instantiated data tree and is not root of
data tree.
Unique identifier of node / subtree in data tree, which provides unambiguous
information, how to reference node / subtree in Instantiated Data Tree.

== Namespaces
YANG defines several namespaces and naming space of YANG is wider then applicable
Binding namespace::
Naming space introduced by Binding Specification for additional properties
and functionality of Binding Specification. This namespaces needs to be separate
- from YANG namespaces in order to not have naming conflict with YANG-derived
- names.
+ from YANG namespaces in order to not have naming conflict with YANG-derived.
Binding Specification v2 uses following namespaces:
=== `container` Statement
+Builders will be located in package "dto"

+
+interface data.FooBuilder {

+
+In situations where we have a containing element which has as its child a single container, we should make it easy to autobox it. This should not be implemented in the interfaces themselves, but rather should be a method in the associated builder.

==== Data Node substatements
Representations of data node substatements are generated according to rules
described in <<data-node-rules>> with following changes:
-
+////
+MS: proposed interface names:
+case - <NodeName>Case
+choice - <<NodeName>Choice
+container, list - <NodeName>
+////
+////
+MC: I would keep Data suffix, but idea about distinguishing cases and choices
+is to think about
+////
* Interface names for `case`, `choice`, `container` and `list`, is suffixed by
`Data` suffix, in order to not conflict with same named groupings inside same
