RE: RFC: Attributes and XML-RPC

imho - attribute support is key to keeping SOAP flexible. Without them,
people will still seek other ways to pass parameters, such as Bennet
Cookson's suggestion of "transport within SOAP schema".

Perhaps my memory fails me but I clearly remember being in

a SOAP meeting at Microsoft where a very wrong headed gentleman

from Redmond (name withheld to protect the confused)

responding to my question "why no attributes". One high

profile XML guy from Microsoft who was present at the

meeting was taken aback by the decisions made. The first 

gentleman expressed the opinion that attributes in general were 

an unnecessary redundancy in the XML spec and he would have

nothing to do with them in SOAP.

---------------------------------------------

 

OK, not supporting attributes makes SOAP simpler in some ways.
But<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office"
/>

given a data or document centric Web Services model I define by Web

Service with WSDL / XML schema.  So, according to SOAP spec, I simply do

not use attributes.  This is great when I create a schema from scratch,

but the problem I have is often I want to use existing schema already in

common use for the type of data my Web Service is dealing with.  For

example I want to build a MyData Web Service to pass around messages with

MyData documents.  But the pre-existing MyData schema uses attributes

which are lost when sent via Web Service frameworks.  

 

This does not simplify, this create a problem that I must invent a new

redundant schema only because the message communication system (SOAP) does
not support attributes although the business processes on either side do.

Must I create a special "transport within SOAP schema?" which encodes
attributes as elements?  How are people currently dealing with this

problem?
