There is no DTD for the project file at present. The above is just used
as a unique identifier.

The .glade XML files should be fairly stable now. libglade is part of
GNOME so we need to keep it stable. 

The .gladep files are only for glade-2. glade-3 probably won't need
them.

I used default values in the original Glade to cut down on the amount of
unnecessary stuff in the XML file. glade-2 does practically the same
thing, except it uses a separate file.

It's too late to change it for glade-2 now.

Yes, it omits some of the common properties if they have default values.
This shouldn't matter, since if they are default values you shouldn't
need to do anything.
