We have an app that uses web services to pass typed datasets to and from the
client and server.  A couple of these datasets contain fields of type
'base64Binary' because of the need to have the client send the server binary
files (usually images).  We've noticed that if the size of the contents of
these base64Binary fields exceeds roughly 3.5M, we get an error when
consuming the web service.  Do any of you know if this is a SOAP document
size limitation or perhaps a base64Binary field size limitation?  If so, can
these sizes be adjusted?

Thanks.
