Check rules for XGR support

[darobin]

There are differences between v1 and v2 here, and I need to check what the status is for XGR support is (low-priority though, since XGRs are gone). Below is what DanB had to say:

1. (The status section) must begin with:
   Include this source code:

   This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of Final Incubator Group Reports is available. See also the W3C technical reports index at http://www.w3.org/TR/.

2. Regarding stability,
   Include this source code:

   Publication of this document by W3C as part of the W3C Incubator Activity indicates no endorsement of its content by W3C, nor that W3C has, is, or will be allocating any resources to the issues addressed by it. Participation in Incubator Groups and publication of Incubator Group Reports at the W3C site are benefits of W3C Membership.

Instead it appears that you include the more generic text for a working draft. And yes, I have told reSpec that this is an Incubator Group report.

Additionally, there is recommended text about text regarding patent policy requirements. For us, the sample text provided is fine:
Include this source code:

<p>Incubator Groups have as a <a href="http://www.w3.org/2005/Incubator/procedures.html#Patent">goal</a> to 
produce work that can be implemented on a Royalty Free basis, as defined in the W3C Patent Policy. Participants in 
this Incubator Group have made no statements about whether they will offer licenses according to the 
<a href="http://www.w3.org/Consortium/Patent-Policy-20030520.html#sec-Requirements">licensing 
requirements of the W3C Patent Policy</a> for portions of this Incubator Group Report that are subsequently 
incorporated in a W3C Recommendation.</p>

But I can add that as a custom paragraph as long as you don't include any statements about patent policy.

If you want to see all of this in context, here's the document I ran through pubrules: http://www.w3.org/2005/Incubator/htmlspeech/finalreport/tempdoc.html
(the reSpec master is http://www.w3.org/2005/Incubator/htmlspeech/finalreport/XGR-htmlspeech.html)

There are other errors, of course, which I am working on, but the boilerplate is inserted automatically by reSpec and is thus outside of my control.

XGRs are now dead. We can remove the code that supports them.
