i.e partial implementation of protocols i.e subsets of the protocol."

Layering does not necessarily mean that there is a single, large protocol
with optional subsets. 

Layering is more general.  It denotes a system in which different facilities
are provided by different parts, with some part drawing on the services of
others or providings services at a higher level of abstraction.

Applied to the specifics of the XML Protocol Working group, the idea of
laying means that not all useful facilities must be built into the base
protocol provided there is a means to define such facilities on top of the
base protocol.  For example, see the recent work on Attachments[1]
demonstrating how to add a capability for MIME-based attachments layered
above the basic SOAP protocol.
