RE: [All] question to implementors (Re: [ACTION-155] (related to [ISSUE-16]) parameters for rules)

Sound good.


I would just add that implementing <its:param> is relatively simple.

Hi all,


I have no objections against the latest proposal from Jirka if we get a clear statement that 

"implementation MUST support its:param"

is no issue, for all implementors in the group. I know that some (e.g. David Filip) are thinking of just wrapping okapi tools for at least some ITS processing, but for the others I'm not sure. So I would propose to close this by asking TCD, DCU, Moravia, Cocomore, Linguaserve, VistaTec, Lucy Software to confirm that they will implement this. Would that be OK for everybody?

Actually declared variables are part of XPath context. As we haven't
said anything about XPath context i ITS 1.0 no variables were declared.
So I think that ITS 1.0 is in this aspect fine (although it contains
another small problems related to XPath integration).

I think that we should say:

- implementation MUST support its:param
- implementation SHOULD provide means for changing its:param and such
means are implementation defined
