My initial thoughts are that it would be Yet Another Markup To Learn, if powerful enough to prevent color space problems.   Perhaps less of a problem to y'all who are real coders and already work fluently in multiple programming languages, but my little router-and-switch-brain segfaults too easy.

But I haven't really thought this out to any degree, so... I could just be full of beans. {grin}
