resource identifiers

[Roy Williams]

Tony and Ray

Looks to me like the Resource ID is getting out of control. It can be used
to cram any amount of stuff in, is that right? Is this a legal ResourceID?

I suggest that you guys are producing enormous expressiveness, but with
little thought for who has to interpret and manipulate.

PS the ISBN number has 10 digits exactly
