Following is a pretty trivial, not to say useless, example of a
Fontconfig file, designed purely to show the kinds of errors that no
DTD can pick up.

Pass:

    <!-- config parsing test -->
    <fontconfig>
        <int>3</int>
    </fontconfig>

Fail:

    <!-- config parsing test -->
    <fontconfig>
        <int>3.5</int>
    </fontconfig>

The error report:

     Fontconfig error: ..., line 3: "3.5": not a valid integer

Here’s the very simple validator script I used:

    #!/usr/bin/python3

    import sys
    import fontconfig

    conf = fontconfig.Config.create()
    conf.parse_and_load \
      (
        filename = sys.argv[1],
        complain = True
      )
    sys.stdout.write("parse completed OK?\n")

And not a DTD in sight.
