Jose, Yes, the idea is to have both an XML and a URL encoding for filters. Unless there's any problem with the BNF grammar you mentioned, it can be considered the final one. The specification being produced should cover everything, not only the XML Schema. Regards, -- Renato On 4 Aug 2006 at 10:16, Jose Cuadra wrote:

Hello,

Just a short question. Does the BNF Grammar that is listed on http://ww3.bgbm.org/protocolwiki/GetInvokedOperations can be considered the final grammar for Filter expressions? And also, besides the XML Schema, are you going to put a grammar like this one for the complete Tapir protocol?

Thanks a lot, Jose Cuadra
