assuming your are not particularly pedantic about unicode characters that might look spacy-like ...
this will work

    fn:exists($elem/@attribute) and  fn: normalize-space( $elem/@attribute ) ne '' 

but it all depends on what you mean by 'has a value'

If I want to make sure that an attribute has a value should I check with empty() and functx:all-whitespace()?
