text/xml vs. application/soap

The current specification says that the MimeType for SOAP/HTTP should
be application/soap

I haven't yet found a production SOAP service that uses application/soap,
they all use text/xml. Many barf, often with no explanation, when the
mime type is application/soap (I've just been playing with the
Sun Forte Soap kit on Tomcat and it does - not sure whether mine
was a current version)

I'm interested in opinions here - what should a SOAP library
do about this? Is there any way to tell whether a service
expects text/xml or application/soap
