Sorry, but I think this is the wrong way to go about this. I think I
understand what you want to achieve, but I also think that by encoding
so much information into a single value, we are making the XML very
hard to parse for normal humans. I would much rather if we split these
4 cases into separate attributes so we have size ( or width, that
proposal makes sense ) that acts like currently, and then have other
non mandatory attributes for the other cases. That will make it much
clearer what is going on I think.

Thoughts?
