1) Make sure the implementation continues to support backslash quoting
so that any characters you introduce with special meanings (comma,
semi-colon, double-quote in that example) can still be used if required.

2) "none" is of course a valid uuid:)  More comma-separation or
re-ordering, perhaps?

3) Whatever final format is agreed here should be supported by dmsetup
as well, so you can both supply the format to dmsetup and ask dmsetup
to display your existing devices in this format.  Choose a format
that makes this easy.
