Your terminology is very confused.
By "Tag" I assume you mean "element".
What do you mean by a "set of empty tags". Do you mean "a set of zero or
more Tag elements in which all the Tag elements have no children"? If
so, test="not(Tag/node())" does it. Your test
Tag = ''
will match the element <Tag><x/></Tag> (which I don't regard as empty),
and it will also return true given <Tag/><Tag>xxx</Tag> (which I
wouldn't describe as a set of empty tags).
