Do you force byte alignment within the PER message?

This will be comical when using crypto in XML, DER->base64->PER.  :)

Why not use DER?  Hand-coded (or probably more accurately, 
IDL-compiler-generated) parser could just skip the tags, in most cases 
the lengths would be single-byte, and you'd get better interop.  Seems 
like that's closer to the 80/20.
