Not that fussy :)

The issue stems from where one of my stylesheets should only output an
attribute provided it had content - quite ofter you would get @label="
", it just so happens that one author decided to use @label="&#160;",
which messed up my output.

It's interesting because afaict the usual methods to check if a string
is empty would all fail in this case.
