I still don't quite follow.  Looking at it from an ISV perspective, this
is my understanding.

ApplicationSoft has some Linux application for doing, say, network
management.  The application is command line only and they want to be
able to break into the market by getting their manager used on as many
Linux installations as possible.  So they code it up relying only on the
LSB spec.  So they look at all distributions that have LSB
certifications and they're reasonably confident that they can then claim
their application runs on all those distributions.

But if their application has a GUI and therefore depends on X and/or GTK
+ and/or QT, then it won't necessarily run on a CGL LSB certified
platform.

If, on the other hand, they coded it up depending on the CGL LSB
profile, they could look at any distribution that was certified CGL LSB
and reasonably claim it worked there as well as reasonably claiming it
works on all LSB distributions since those distributions would include
everything in the CGL LSB profile as well as GTK+ and QT.

Or am I in need of more coffee this morning?  That's always a
possibility.
