In the interest of fairness, here is the exhaustive (if memory  
serves) list of issues I've encountered while using RelaxNG:

  - One processor accepted <div> everywhere (since the simplification  
rules just replace it with its content) while others noted that it  
was an error to have it in certain locations. This constitutes the  
one and only genuine interoperability issue I remember seeing in  
years of usage (since a schema accepted in one case was rejected in  
others), and it concerns an element that has no semantics whatsoever  
and no impact on validation (it is just used to document and refer to  
logical sections of the schema).

  - Jing runs with DTD compatibility on by default whereas others  
don't. This isn't an interoperability issue since setting the right  
option will turn it off, but it's a PITA because one has to remember  
that, and also because DTDs are for weenies (hey, it's Friday :).

  - The error messages are inconsistent between implementations.  
Again, this is not an interoperability problem (since you will always  
get an error) but it can be a bit painful.

Don't get me started on the problems I've faced with XML Schema  
implementations :-)
