So if i'm reading you correctly, the following:

match="foo[@bar!='']"

1. <foo>x</foo>
2. <foo bar="">x</foo>
3. <foo bar="x">x</foo>

should match #3 only?

and are these two expressions equivalent?
match="foo[@bar!='']"
match="foo[not(@bar='')]"

boolean(@rend) is true if the attribute exists
not(@rend) is true if the attribute doesn't exist
@rend='' is true if the attribute exists and has the value "".
