Subject: [PATCH] Changed <xref> with endterm to process the children nodes and
 not just the text by calling a new mode="endterm" template.

Also changed <link> to process its endterm if the element content
is empty.

Also changed the first use of name() to local-name() to
match the others in the file and in html/xref.xsl.
