/**
 * Base class for E4X XML attribute-access or property-get expressions.
 * Such expressions can take a variety of forms. The general syntax has
 * three parts:
 * <ol>
 *  <li>optional: an {@code @} (specifying an attribute access)</li>
 *  <li>optional: a namespace (a {@code Name}) and double-colon</li>
 *  <li>required:  either a {@code Name} or a bracketed [expression]</li>
 * </ol>
 *
 * The property-name expressions (examples:  {@code ns::name}, {@code @name})
 * are represented as {@link XmlPropRef} nodes.  The bracketed-expression
 * versions (examples:  {@code ns::[name]}, {@code @[name]}) become
 * {@link XmlElemRef} nodes.<p>
 *
 * This node type (or more specifically, its subclasses) will
 * sometimes be the right-hand child of a {@link PropertyGet} node or
 * an {@link XmlMemberGet} node.  The {@code XmlRef} node may also
 * be a standalone primary expression with no explicit target, which
 * is valid in certain expression contexts such as
 * {@code company..employee.(@id &lt; 100)} - in this case, the {@code @id}
 * is an {@code XmlRef} that is part of an infix '&lt;' expression
 * whose parent is an {@code XmlDotQuery} node.
