New Issue: Add ContactInfoAddresses Element

Currently if one found a federation metadata document on the park bench and had questions about it that required human assistance you would need a priori knowledge to find a contact person. Federation metadata should include a well defined reference to associated contact info.

Proposal:
Add a new section preceding the example document section 3.1.16.

3.1.xx ContactInfoAddress Element

The OPTIONAL <fed:ContactInfoAddresses> element allows a federation metadata provider to specify the endpoint addresses to be used for contacting the metadata provider for further details on the services and capabilities described in the metadata. This element populates the [Federation Metadata] property.
The schema for this optional element is shown below.

<fed:ContactInfoAddresses>
( <fed:WebPage> xs:anyURI </fed:WebPage> *
<fed:Email> xs:anyURI </fed:Email> * ) +
...
</fed:ContactInfoAddresses> ?

/fed:ContactInfoAddresses

The content of this OPTIONAL element is one or more elements that provide references to web pages with contact info about the federation services and/or an email address to use as a contact point.
This element allows other attributes to be added so long as they do not alter the semantics defined in this specification.

/fed: ContactInfoAddresses/fed:WebPage

This element of type xs:anyURI MAY appear 0 or more times, it’s content should be a valid [HTTP] scheme URI that resolves to a web page with contact information regarding the federation services and/or metadata document.

/fed: ContactInfoAddresses/fed:Email

This element of type xs:anyURI MAY appear 0 or more times, it’s content should be a valid [mailto] scheme URI regarding the federation services and/or metadata document.
