47 * The effect of a "uses" reference to a grouping is that the nodes
48 * defined by the grouping are copied into the current schema tree and
49 * are then updated according to the "refine" and "augment" statements.
51 * Our argument is composed of QNames in the current schema tree's namespace, but the grouping may have been
52 * defined in a different module -- and therefore it knows those children under its namespace. Adjust the path
53 * we are searching if that happens to be the case.
