Title: Introduction misleading

Description: The last paragraph in the introduction to the WS-Policy 1.5
Framework discusses WS-Policy 1.5 - Attachment. However, I believe that it 
is
somewhat misleading in its intent. Specifically, I think that the 
terminology
used should be consistent with the defined terms in our glossary. 
Secondly, I
believe that we should reorder the sentences to make it clear that 
WS-Policy
1.5 Attachment defines certain attachment mechanisms and policy scopes and
subjects and that other specs are free to define OTHER attachment schemes 
for
policy subjects and scopes not covered in WS-Policy 1.5 Attachment. 
Otherwise,
we are effectively encouraging a potential interoperability nightmare.

Justification: see above

Type: editorial

Proposal:

change:
Web Services Policy 1.5 - Framework does not specify policy discovery or 
policy
attachments. A policy attachment is a mechanism for associating policy 
with one
or more policy scopes, where a policy scope is a collection of policy 
subjects
to which a policy may apply. A policy subject is an entity (e.g., an 
endpoint,
message, resource, interaction) with which a policy can be associated. 
Other
specifications are free to define technology-specific mechanisms for
associating policy with various entities and resources. Web Services 
Policy 1.5
- Attachment [Web Services Policy Attachment] defines such mechanisms,
especially for associating policy with arbitrary XML elements [XML 1.0], 
WSDL
artifacts [WSDL 1.1, WSDL 2.0 Core Language], and UDDI elements [UDDI API 
2.0,
UDDI Data Structure 2.0, UDDI 3.0]. 

to:
Web Services Policy 1.5 - Framework does not cover discovery of policy, 
policy
scopes and subjects, or their respective attachment mechanisms. A policy
attachment is a mechanism for associating policy with one or more policy
scopes. A policy scope is a collection of policy subjects to which a 
policy
applies. A policy subject is an entity (e.g., an endpoint, message, 
resource,

WSDL

2.0,
UDDI Data Structure 2.0, UDDI 3.0]. Other specifications are free to 
define
either extensions to the mechanisms defined in Web Services Policy 1.5 -
Attachment, or additional mechanisms for purposes of associating policy 
with
policy scopes and subjects not covered by Web Services Policy 1.5 - 
Attachment.
