Take a look at the XML Schema spec[1]. I intend that the abstract model
for WSDL will be along similar lines. I will be working on it this week,
so expect that section of the spec to change drastically

Hi Sanjiva,

My initial reaction is to say no, the abstract model should not be
coupled to the infoset. But then I am wondering what does this really
means. Is the difference only in terms of terminology ("property" vs.
EII?) or is it more profound? Wouldn't both approaches essentially model
a (DOM) tree? Isn't the infoset already a suitable model?

The cut we have done for SOAP 1.2 is to describe the
semantics/processing [1] separate from the syntax [2]. Would a similar
model work for WSDL?

Taking a specific example from your latest draft -section 2.2 [3]-,
would it work to keep to keep only paragraph 1 and move the rest to
section [3], whilst adding a longer description of what a message

I realize I am raising more issues than providing answers... What do you
