The problems that apply to *my* situation and *my* technology.  Also, 
violations of the in-house design style guides that only I use -- for 
instance, require a partnum attribute whose value exists in the 
purchasing database.

In other words, generic DRC is largely pointless.  DRC should be 
implemented as a DRC engine and a rules database.  Of course, one hopes 
that a (or two or three) good, reasonably generic rule sets can ship 
with the release.  End users can start with that and tweak to their own 
needs.

The trick, it seems to me, is to come up with a clean and readable 
syntax for the rule set.  The language needs to be declarative at its 
core, and allow user plug-ins written in C (so that I can run SQL 
queries against my parts database, for instance.)
