Re: Problem with data in interleave in RELAX NG validation

Hi!

This remains unfixed.  I have absolutely no idea what’s going on 
in the interleave validation code.  Daniel, could you please put 
together some minor documentation on how the interleave validation 
code works?  It’s very complicated.

Thank you,

  Nikolai
