/** The lang function returns true or false depending on whether the language of
the context node as specified by xml:lang attributes is the same as or is a
sublanguage of the language specified by the argument string. The language of
the context node is determined by the value of the xml:lang attribute on the
context node, or, if the context node has no xml:lang attribute, by the value
of the xml:lang attribute on the nearest ancestor of the context node that has
an xml:lang attribute.**/
