SDL Trado Studio 201X: XML and embedded content: Tag pairs not processed as pairs?


Does anybody know if tag pairs defined in embedded content processing in XML filetypes are not processed in pairs? If trying to  break up [shortcode a='b' ...title='TRANSLATE-ME' b='c'] I get the pairs marked up but also all other closing patterns are shown as placeholder tags!? There is no other rule activated for content processing elsewhere.

Any ideas?

Thanks, Daniel
