Proposed positive text for XML Base

I took Noah's excellent wording[1] and semantically NOTed it.  My attempt 
follows.  Please note that this wording defines that relative URI's ARE 
interpreted according to xml:base, therefore implementations must support 
xml:base.  It seems to me that an application that doesn't support xml:base 
but supports relative URIs is an undefined state.

BASE URI's and Relative URI Resolution
--------------------------------------
"This version of the SOAP specification supports the W3C XML Base 
Recommendation. The xml:base attribute MAY appear on the SOAP-ENV:Envelope, 
SOAP-ENV:Body, SOAP-ENV:Header, or SOAP-ENV:Fault elements.

The XML Base specification provides a standard Base URI for the contents of 
the SOAP-ENV:Body or other header entries.  Specifications for particular 
applications of SOAP, as well as specifications for transport bindings, 
header entries and/or body entries MAY define the interpretation of 
relative URI's within such body or entries additionally. In the absence of 
such additional specifications, the resolution of relative URI's appearing 
within the contents of a body or other header entry is defined by XML Base.

Relative URI's MAY be used as values for attributes or elements (such as 
SOAP-ENV:Actor, SOAP-ENV:EncodingStyle) defined by this specification; if 
such values are used, their resolution to absolute URI's is defined 
according to the XML Base Recommendation.

Namespace declarations for the namespaces used in this specification (such 
as http://www.w3.org/2001/06/soap-envelope) MUST be provided as absolute 
URI's. Element or attribute names qualified with relative URI namespaces 
are not recognized as matching the absolute names mandated by this 
specification."
