Hi Aaron,
Did you mean to paste the same link twice?
Were you referring to the RequestStorable capability?
Thanks,

The javadocs will help:
http://source.sakaiproject.org/release/2.6.2/apidocs/index.html?org/sakaiproject/entitybroker/entityprovider/capabilities/package-summary.html
In this case I think you want this one:
http://source.sakaiproject.org/release/2.6.2/apidocs/index.html?org/sakaiproject/entitybroker/entityprovider/capabilities/package-summary.html
Confluence only has the basics. The detailed docs are in the javadocs
themselves.
Hope this helps
