Re: [wsrf] Potential incompatibility WS-R / WS-RP

[Ian Robinson <ian_robinson@uk.ibm.com>]

Kirk, nothing in WS-RF has changed with respect to the relationship between
a resource properties document and its resource properties. Since we began
this TC it has been the case that "The complexType defining the resource
properties document MUST define a collection of zero or more child
elements, called resource property elements. Each child element MUST be a
GED."
At the recent F2F we simplified what it meant to be a resource properties
document but the requirement for "zero or more" resource properties did not
change. In the case where a WS-Resource has no resource properties and
additionally supports the GetResourcePropertiesDocument operation, then any
GetResourceProperty message would elicit a response of
InvalidResourcePropertyQNameFault. But it should not be the requirement
that a WS-Resource MUST support GetResourcePropertiesDocument as its only
mandatory operation since this may involve the exchange of large XML
documents for some WS-Resources.

Given the decision in WS-R to separate the resource property document
from resource properties such that a RPDoc MAY contain resource
properties, is there an incompatibility with the following statement in
WS-RP (vers 09, lines 358-360):

Any interface that includes a resource properties document type
declaration (/wsdl:portType/@ResourceProperties) MUST also include the
GetResourceProperty message exchange (operation) defined in this
section.

Should the requirement now that the interface MUST include the
GetResourcePropertyDocument?
