9 * Intermediate representation of a YANG file. This is an Abstract Syntax Tree equivalent to ParseTree we get from
10 * ANTLR, except it is immutable and has a denser in-memory representation due to it not containing any metadata which
11 * is not required for the purposes of statement inference.
14 * The main entrypoint into this package is {@link org.opendaylight.yangtools.yang.parser.rfc7950.ir.IRStatement}, which
15 * represents a single YANG statement. Every YANG file is required to contain exactly one top-level statement,
16 * {@code module} or {@code submodule}, hence an IRStatement also represents the significant contents of a YANG file.
