XML encoding issue

["Graeme Merrall" <dasfreak@gmail.com>]

Not quite sure what's going on here so would appreciate some help.
I'm connecting to a SOAP service and the service receives and responds
correctly to a request. I've confirmed this by looking at teh HTTP
headers flowing backwards and forwads. However, the soap class returns
a fault with the text "Error: XML error on line 1 col 4 byte 4 not
well-formed (invalid token)" I've tried various options of literal vs
document but no joy.

Any pointers appreciated.

Cheers,
Graeme
