These doc bugs are fixed in the wiki. I don't think there's anything
particularly contentious to be reviewed but it is slightly more
complicated than it needs to be. I'll leave it at that.

I think there is a deployment issue here. Some federations document
the use of ChainingMetadataProvider while others do not. I know of at
least one federation document that does not use
ChainingMetadataProvider but neither does it use sortKey on the bare
metadata providers. AFAICT by reading *our* documentation, that
results in an unspecified search order. I'm pretty sure that's not
what the author of the federation document intended.
