Representation Header technologies as W3C Recommendations. I believe
these are likely, over time, to emerge as replacements for
SOAP+Attachments in the marketplace. Most of the major SOAP vendors I
know expect to provide support for these technologies in future products
(NOTE: I should say for the record that this is not an official statement
of support or a formal commitment to support these technologies in any
products shipped by my employer, IBM; I can say that we have actively
supported the development of these recommendations.) A well-optimized
implementation of MTOM-enabled intermediares would provide for efficient
inspection of headers, and XOP/MTOM provide for better unification of the
file data into the model of the XML envelope.

be sent. In general, XML documents don't nest. For example, if the
document to be transmitted has an internal subset DTD (I.e. a DTD in the
document) you can't send it as a direct child of <soap:body>. If you need
to preserve the encoding of your document (UTF-16 SHIF-JIS) and it's
different from that of your envelope, then you also can't do a simple
nesting. Same for documents with entity references, which for the most
part are not allowed in the body of a soap envelope. For these reasons, a
general solution for a document management system would be to use MTOM,
perhaps with the new representation header, or if you prefer
SOAP+Attachments as you suggest.

webMethods, I would use webMethods Integration Platform  with the
appropriate ERP Adapter  and JDBC Adapter to provide integration from
ERP systems to databases. This solution would not require IIS or a
separate application server. The ERP Adapters often provide better
integration to the ERP systems than the vendor's SOAP interfaces do, or
the ERP SOAP interfaces are OEMed versions of webMethods products.

to process the SOAP message (like looking at the headers) without
requiring them to decode the attachment. If you are not going through an
intermediary, sending the XML as the SOAP body makes life simpler and
you don't lose anything.

SOAP messages that correspond to that WSDL as a web service.
