Currently the provision service endpoint bsgra_guids returns results in the format:

<?xml version="1.0" encoding="UTF-8"?>
<bsgra_guid>6b0c73c0-bsga-kali-kali-001b7744e04a</bsgra_guid>

This is useful for now because the resource only supports querying by name and instance.  However, I have been tasked with providing a gadget to show all provisions.  This requires more general queries against the bsgra guid resource.  Therefore, I am proposing changing the output to:

<?xml version="1.0" encoding="UTF-8"?>
<bsgra_guids>
<bsgra_guid_entry>
<bsgra_guid>6b0c73c0-bsga-kali-kali-001b7744e04a</bsgra_guid>
<name>kalivo</name>
<instance>kalivo</name>
</bsgra_guid_entry>
</bsgra_guids>

The new format provides more information necessary to associate each BSGRA GUID to its respective name.instance.  All the clients I have investigated have accessed the bsgra guid by using the XPath "//bsgra_guid".  Therfore, because this routine will still get the correct bsgra_guid, the new format should be backwards compatible with the old one.

Alternatively, we can preserve the format for the service if both the name and instance are provided.  This well guarantee that all previous clients will not break due to the changes.  However, the new format will allow for better feature expansion in the future if we ever need to add more properties to a bsgra_guid.

Please let me know if this new format will cause problems with existing service provision clients.
