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=" ", 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.
