We've touched on this fairly contentious subject a few
times, including at our F2F.

I've shied away from a proposing a core set of tools not wanting to
risk saying '.NET 2.0 and JAXB are of course far more important than
anotherDatabindingTool just incase it turns out anotherDatabindingTool
is 'big in Japan' (by which I mean core to a large market place
outside of my personal sphere of knowledge).

Of course if we had a good representative set of vendors
participating in the working group, this task could
be a lot easier. Maybe your approach of listing tools important
to BT, or whoever, may flush out tools wanting to be on the list.

Again, 'popular' is the difficulty here, as is how far back
in time do we go - what if Axis 1.1 is critically important to
someone on the Working Group, or following our work?

The charter cites 'state of the art' but this term can be taken
several different ways - either the best available, the median
or lowest common denominator of features across all toolkits,
be they mainstream or niche.

Can we pick the lowest version of these - based on a lazy assumption
that newer versions are likely to support more patterns?

OK ..

not a databinding tool (as PaulB notes).

Oracle has a raft of toolkits, I'd be interested to see
an XML to Database mapping tool included.

This list seems to include toolkits used by BT, and possibly
tools used by well known customers, but may not really
capture the market place of tools potentially used by
customers. Hence the difficulty of this issue and process.

What about Ajith's WSO2 work or Peter's LMX? then there is 
Castor, JiBX, to name but three others.

What do we do about mainstream tools we don't have licenses
or environments to run - I don't have much personal experience
with SAP or TIBCO software, for example.

Yup, it's contentious, but maybe building a list of tools and
getting the community to provide more is the best way forward,
but what's our criteria for including or ignoring a toolkit,
especially one which lowers the lowest common denominator?

Is it useful to us or users of our specification if we elect to
ignore Axis 1.3 because it ignored xs:choice, even given how
widely deployed it is likely to be?
