I'm a bit late to this thread but here's my input;

I seem to remember in SOAP 1.0 that the value of the SOAPAction *had* to be
the namespace URI + # + localname of the first child element of the Body.
This was I *thought* done to allow firewalls etc. to figure out ( broadly )
what the message was attempting to do and filter accordingly. All the SOAP
impls I've written have checked that the SOAPAction matches the first child
of the Body and if it doesn't throw a fault.

In SOAP 1.1 this requirement was relaxed ( it became more
vague/woolly/underspecified ( delete as appropriate )). Why?
