In my experience is better than that.  We have customers in
production that regularly interop among our product, IBM, Microsoft,
and some others.

It's a subtle point, but unless you use something like WS-Sec, than
you cannot sign arbitrary XML content unless you change every
single schema to include an enveloped XML Dsig.  That's not feasible.
Possible, but not feasible; you really do need WS-Sec and SOAP if you
want to exchange messages with end-to-end content integrity.
