Allowing references to as-yet-undefined namespaces is an important part
of the extensibility. As extensions are defined, it allows publishers
to write documents using the new extensions, yet remain compliant with
the current version. Without this, it would be suicidal for a publisher
to take advantage of a new extension -- his document would be seen as
invalid by any implementation that hadn't yet been updated to understand
And how does this differ from the non-XML SPF-based
syntax's extensibility? Wouldn't the SPF syntax be similarly
extensible if it were to simply ignore record statements
that it did not (yet) understand? From what I understand,
that is the difference; CID ignores unknown data, SPF treats
the whole record as suspect. Am I correct in that assumption?
