SoapExtensions definitely work in Mono, at least with the 1.1 profile.
Two samples are even part of the XSP's test site:


Note how these extensions are programmed: they rely on an attribute
which has to be attached to the web service class.

The extensions are not invoked when the web service methods
are called interactively from the Web Service Description Test Page.
This might be a bug.
