Re: [office-formula] Proposal: Identifying nonstandard functions

I'm replying to the office list rather than the office-formula list, because 
I'm not a member of the Formula SC.

I agree to Rob. I think a registration business is outside the scope of the 
OpenDocument TC, and I believe also outside the scope of OASIS.

I further think we have to differ between using XML namespaces for the 
identification of extensions/implementations, and the use of 
[prefix]:[local-name] syntax of XML namespaces. If it is not possible or 
reasonable to use a colon within formulas (and I have no doubts that this is 
the case), then I think it is better to use a dot instead and to keep the 
other semantics of XML namespaces, then it would be to define a new 
extension/identification method.
