I was thinking about the latter case, that there should not be necessary
to go and register every value before you can use it.  The alternative would 
be to define a list containing all the values that we are aware of now, and
let vendors with odd values register their own later, but that is
definately more messy.

Defining a separate syntax seems the simpler way to solve this. Also, an
XxY syntax may well come in handy for other attributes in the future.
