Update on this issue:
Line 715 of DPWS CD1 introduces Section 5.4 by mentioning DEVICEs as
the main target of the policy assertion. However, the rest of the
section defines requirements which apply to SERVICES:
To indicate that a DEVICE is compliant with this
profile, this profile defines the following WS-Policy [WS-Policy]
assertion
Proposed resolution (changes in red):
To indicate that a SERVICE
is compliant with this
profile, this profile defines the following WS-Policy [WS-Policy]
assertion
Important note:
The proposed resolution clarifies the use of WS-Policy assertions for
HOSTED SERVICES (a specialization of SERVICE), which must be described
through WSDL documents (per section 5.3), however it does not really
solve the issue for DEVICEs, as no DPWS requirements constrain them to
be described through WSDL documents (all requirements in Section 5.3
apply only to HOSTED SERVICES). Requirements in section 5.4 are more or
less meaningless in the absence of a WSDL document.

Subject: NEW Issue - Clarify use of WS-Policy for devices
Please defer discussions on this issue until a time this issue is
accepted and is assigned a number.
Document: DPWS
Location (defaults to line number): 831
Owner: Antoine Mensch
Description:
it is not clear whether R2037 applies to devices, hosted services or
both. While hosted services have an associated WSDL document which can
be extended with WS-Policy information, it is not clear from the
specification that devices have an associated WSDL document. Currently,
the WSDL section of the specification only mentions hosted services. If
devices should have WSDL documents associated to them, rules for
writing
them should be explained, as the semantics of WSDL elements applied to
devices is not obvious.
