Indeed - this is ultimately all boils down to the gotcha of xquery
returning element and attribute nodes instead of the string values of
those nodes ala xslt. (my test framework uses xquery in the junit
tests and I still often get caught by this when I forget /string(.) on
the end of simple xpaths)
Like all gotchas you will get got until you know about them. The
thing is, xquery has a load more, so if they are all played out like
this it should be fun.
