>> during the teleconference of 16 April, where it received broad  
>> support.
>> I am currently working on a proposal and technical framework for this

>> Since the work will be taking place within SC 34, it is natural

>> the RELAX NG schemas (and XProc) to perform XML validation of  
>> packages.
>>
>> It is therefore vital that all the RELAX NG schemas associated with
>> ISO/IEC 29500 are correct, since they will be used as the backbone of
>> document conformance testing.
