agree on this and indeed what I envision is something different from  
traditional "profiles".
I'm thinking more about a "meta-profile" that can be used by vertical  
industry groups (or single companies) as base for their work.
Such "meta-profile" will still help to minimize fragmentation suggesting  
how things could be combined togheter to make a product or a vertical spec.

If the variables are identified beforehand, and all different profiles  
following this meta-profile have the same structure, is probably easier  
for people to understand the differences and for implementers to follow  
them.

Also on this, sometimes is difficult to find values that fits every  
ecosystem, but if these variable are extracted in a common place, is  
immediately clear what people have to look at when reading one of the  
profiles generated by this meta-profile. Also there are mistakes that have  
been done in the past when doing "profiling" and that hurts  
interoperability; this meta-profile should clearly highlight what such  
mistakes are and why they should not be done.
