Re: issue: optional parts in <message>?

OK, thanks; that helps. Question:

Does the restriction on base64 imply that this is going to be sent in
XML as base64 encoded data? The abstract description obviously
needs to be above the wire representation and hence should not pick
any specific format (that's what the binding will do).

Basically, there is no indication at the abstract level whether the
image will be sent inline with the SOAP envelope, as an attachment
or sent by reference by just sending the URI to it.

Thanks,

Sanjiva.
