32 Returns the local part of the name of $srcval as a string that will either be the zero-length string, or will have the lexical form of an NCName.
33 If the argument is omitted, it defaults to the context node.
34 If there is no context node (that is, if the context item is not a node), the function returns the zero-length string.
35 If the argument is supplied and is the empty sequence, the function returns the zero-length string.
36 If the target node has no name (that is, if it is a document node, a comment, or a text node), the function returns the zero-length string.
37 Otherwise, the value returned will be the local part of the expanded-QName of the target node (as determined by the name accessor in the data model).
38 This will be a string whose lexical form is an NCName.
