public class XmlElemRef extends XmlRef
[expr] member-ref expression. The node type is Token.REF_MEMBER.
Syntax:
@opt ns:: opt [ expr ]Examples include
ns::[expr], @ns::[expr], @[expr], *::[expr] and
@*::[expr].
Note that the form [expr] (i.e. no namespace or attribute-qualifier) is not a legal
XmlElemRef expression, since it's already used for standard JavaScript ElementGet
array-indexing. Hence, an XmlElemRef node always has either the attribute-qualifier, a
non-null namespace node, or both.
The node starts at the @ token, if present. Otherwise it starts at the namespace name.
The node bounds extend through the closing right-bracket, or if it is missing due to a syntax
error, through the end of the index expression.

AstNodeNote: if the parser was in error-recovery mode, some AST nodes may have null
children that are expected to be non-null when no errors are present. In this
situation, the behavior of the toSource method is undefined: toSource
implementations may assume that the AST node is error-free, since it is intended to be
invoked only at runtime after a successful parse.
