Surely it would make much more sense to have all the predefined class 
names start with a dash? After all, XHTML5 is not yet standardised, 
whereas people have been using all sorts of random class names for years 
- but, I suspect, mostly without a leading dash.

This is similar to the C/C++ thing of having reserved symbols like 
__LINE__ start with an underscore.
