That's correct.  I believe (but am not 100% certain) that those files
are "definitions" for the settings (and types) that mate-panel support:

     <key name="max-recent-items" type="i">
       <range min="-1"/>
       <default>10</default>
       <summary>Maximum number of recent documents displayed in the Places menu</summary>
       <description>Maximum number of recent documents that are displayed in the Places menu at a time. If this is set to -1, all known recent documents will be displayed.</description>
     </key>

type="i" is integer, type="u" is unsigned, type="b" is boolean, etc.

I believe what the error message is saying is that your current theme is
not supplying a value for max-recent-items, but the gschema says there
should be one.

That's generated by glib-compile-schemas(1).  From my understanding, it's
basically just a binary cache of all of the XML schemas in that directory.

The Gsettings classes in glib can read that binary blob.  I'm not sure if
there's a "decompile" tool, but I kind of doubt it.

You could try move that file aside and then regenerate it with
glib-compile-schemas and see if you get an identical file.

At one point I understood the theme support better, but it has been
so long since I looked at it that I don't recall how it all works.  If
you do figure out where the theme you're using is lacking settings, please
do report back to the list.
