How can I add <references> to a metadata repository?
When I add a section
<references size='2'>
<repository uri='http://www.example.com/eclipse/updates' url='http://www.example.com/eclipse/updates' type='0' options='0'/>
<repository uri='http://www.example.com/eclipse/updates' url='http://www.example.com/eclipse/updates' type='1' options='0'/>
</references>
to content.xml
this update site is listed in the Available Software Sites.

Can some task during PDE build do this?
Are the details of <references> documented somewhere?
Is there some other tooling in p2 to add this to content.xml?

Site.xml files can be used to categorize your repository. You specify it
using "p2.category.site"
http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse. pde.doc.user/tasks/pde_p2_productbuilds.htm

I've never tried this myself, but it appears that old style update sites had
an attribute "associateSitesURL".
There is some documentation here:
http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclips e.platform.doc.isv/reference/misc/update_sitemap.html
This should be a relative url which points to an xml file which lists the
assoicated sites.

Looking at the code p2 publishing code
(SiteXMLAction#getFeatureToCategoryMappings), it appears that if the
site.xml contains the associateSitesURL, then these URLs will be read and
set on the repository as references.

Using the "p2.category.site" property to categorize your build will probably
add the references to the internal build repo and not the final result repo
because I don't believe these references are mirrored between repos.

You probably have make an extra call to add these to the final repo, you can
do this with the <eclipse.publish.featuresAndBundles/> ant task
http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse. pde.doc.user/tasks/pde_p2_buildtasks.htm
<eclipse.publish.featuresAndBundles repository="file:/build/repository"
site="file:/build/site.xml" >

It may also be possible to use the UpdateSite Publisher application
