Dear colleagues,

I had a chance to contribute to the RELAX NG schemas for XML 
signature and encryption.  The result is "XML Security RELAX NG Schemas",  
available at:


ISO/IEC 29500-2 (OPC of OOXML) uses XML signatures (but not encryption).  


Since ISO/IEC 29500- contains RELAX NG schemas (non-normative) for OPC,
I believe that we should revise our schemas when W3C publishes the final
version of "XML Security RELAX NG Schemas".  I will submit a defect
report about this when the final version is ready.

I am still a novice of digital signature and encryption, but I have come to wonder 
why OPC does not use XML signature 1.1 and does not reference to exclusive
C14N, XML Signature Properties, and so forth.  Should I submit some
defect reports?
