Hi,

I committed some changes to the backend authentication spec.

					https://bitbucket.org/openid/mobile/commits/cfc0db39340898f247caad2fb1553fb7ba7092d5

Some changes were triggered by warning by xml2rfc, some fix typos.

I hope the process I chose, editing in Bitbucket and committing, is OK for the group.
The changes don't change the spec in material ways.

Could someone, Florian or Gonza, please click the approve button on the commits?!

Cheers
Axel
