Re: EXI for HTTP? Re: Efficient XML Interchange (EXI) LC spec addresses ISSUE-30 (binaryXML-30)?

Hi Mark,

Not neccesarily. EXI Is just a more compact binary data format. It  
does not dictate a particular data model or API. However, one of the  
advantages of being an XML technology, is that you could use any of  
the existing XML APIs or data models to access the EXI data if they  
were present, familiar or otherwise convenient. Of course, you could  
also leverage other XML technologies like xpath or xquery if desirable.

      Cheers,

      John
