Dear Group,

Ref: <http://lists.w3.org/Archives/Public/public-wai-ert/2008Sep/0002>

 From reading some of the POWDER documents, it seems that their work on 
grouping resources may be very useful for EARL. For example, we may be 
able to group several resource that share the same HTTP headers. This 
would however need further discussion and it may complicate things.

Unfortunately however, it seems that there is currently no direct method 
for relating POWDER descriptions to technical standards (such as WCAG) 
or to testing reports (such as EARL). It also does not provide means to 
reference the evaluation methodology or complaint mechanisms etc.

In Example 2-1 of <http://www.w3.org/TR/powder-dr/> it says:

10     <descriptorset>
11       <ex:color>red</ex:color>
12       <ex:shape>square</ex:shape>
13       <displaytext>Everything on example.com is red and 
14       <displayicon src="http://authority.example.org/icon.png" />
15     </descriptorset>

It seems that any additional descriptions about the assertions need to 
be provided in separate namespaces. In this case it is in "ex:".

However, since one of the use cases for POWDER is certification, it may 
be important to provide the following optional properties:
  # <standard> - references a standard or requirement for the certificate
  # <test-report> - links to test reports, such as EARL (not exclusively)
  # <methodology> - the process followed to certify (if this is public)
  # <contact> - a URI for someone to contact or for a complaints system

Not sure if all these make sense but at leas the first two seem pretty 
important to model certificates (more important than an icon to me).
