/ Erik Bruchez <ebruchez@orbeon.com> was heard to say:
|    The main point I am making here is that I do not think we should
|    consider the inclusion of features such as conditionals or multiple
|    inputs and outputs based on a "streaming" requirement.

Right.

| o PSVI: an implementation should be able to pass PSVI information
|    between components, but a non-PSVI-aware implementation should also
|    be conformant, as mandatory PSVI support can be quite contentious a
|    requirement (based on reactions to schema-aware XSLT 2.0's PSVI
|    requirement, in particular).

Right.

| o We should make a distinction between the underlying technology used
|    (DOM, SAX, etc.) and the information content being passed. It seems
|    to me that it is important that we discuss the latter, while the
|    former should probably be outside the scope of the spec.

Yes.

| o To follow-up on Norm's "to the extent possible", the WG should
|    determine whether there is a *minimal* set of information content
|    that every conformant implementation is required to support. As
|    suggestions, such content could be:
|
|    o the XML infoset
|    o the information set passed on a SAX ContentHandler (which is a
|      subset of the XML infoset)
|
|    Determining such a minimal information content, along with support
|    for a "core library" of components (XSLT, XInclude, as suggested
|    above) would be a step toward ensuring that there is an actual set
|    of use cases that all conformant implementations will be able to
|    actually run.

I think we have to define a core library that satisfies our use cases.
It's likely that we'll be able to derive a minimal set of information
From that, but I'm not sure we'll ever have to.

                                        Be seeing you,
                                          norm
