Issue Description:

Activation Service should be able to communicate inability to create a 
context


Issue Details:

Faults in WS-C should be divided into two categories: those which apply 
to the process of context creation and
registration (or which apply to the misuse of the conversational channel 
created by registration), and those
which are basic faults available to all coordination protocols.

Under the first category, it seems reasonable to expect that an 
Activation Service may not be able to satisfy a request to create a 
CoordinationContext. Reasons might include: capacity constraints; 
authorization failure; resource failure (loss of connection to 
persistence store, for example).


Proposed Resolution:

1) Insert new Fault description (order in section an editorial matter) 
as follows:

4.x Cannot Create Context

This fault is sent by the Activation Service to the sender of a 
CreateCoordinationContext to indicate that a context could not be created.

Properties:

[Code] Sender
[Subcode] wscoor:CannotCreateContext
[Reason] CoordinationContext could not be created.
[Detail] unspecified


2) Add new enumeration to schema type ErrorCodes:

      <xsd:enumeration value="wscoor:CannotCreateContext"/>
