Comment:

6.2.2.2: <meta> Attribute Details

Current text:
" Either the name or the http-equiv attribute has to be specified. If
neither of them is specified, or if both are specified, an error.fetch event must be thrown."

Proposed text:
""

I think that this part of specification is in contradiction with section 9.5.2: "Document Initialization Errors", which states: "Errors that occur during documentation initialization (elements that occur in the CCXML document before <eventprocessor>) occur outside of CCXML's event handling mechanism. These errors MUST cause the CCXML thread of execution to terminate and notify the platform of the document error."

The element <meta> occurs in the CCXML document before <eventprocessor>, so it should be handled according to section 9.5.2.
