Bug fix:

Constraint was looking for _all_ descendant text nodes of eg element,
not just child text nodes. That means that if there is any phrase-level
encoding in an eg element there is more than one text node that has (for
example) position()=last(), and the XPath fails because only one item is
allowed as the first argument to matches().
