Comment 2 for bug 979413

I've committed a fix for this, changing:

<xref linkend="ch_identity_mgmt">

to

<xref linkend="ch-identity-mgmt-config">

While it's true that the file that's linked to is in ../common/ch_identity_mgmt.xml, xrefs actually point to the xml:id attribute on the target element, without any reference to the file containing that element.

I also fixed a number of other minor validation errors.
