b969e1c7 added a reference to this file
and a command to generate it into tests/mime-detection/list, but didn't
commit the generated file itself. Now when test-mime fails for some
other reason (e.g. after adding a failing test case), the following
error message is printed:
Could not open /path/to/shared-mime-info/tests/mime-detection/test-not-dtshd.txt

Presumably when the test file does not exist, the intended 'data' test
does not run. The testing system should be improved to report such
nonexistent file issues as test failures.

Section 3 of the MRML specification states "it is XML-based, meaning
that standard parsers can be used to process the communication
messages."

Another ninja implementation that works is samurai

Look for `<key>_SPCommandLineArguments</key>` in addition to plist root
element to distinguish from other property list XML files.

Our offset specifiers aren't that fancy, so this can trigger on files
that have the above string ´_before_ `<plist version="1.0"`, but those
should be quite pathological cases.

Start offset 34 is length of `<plist version="1.0"><array><dict>`, 384
is arbitrary guesswork.

Matching just 0x64582025 within the first 18725 bytes of any file is
prone to false positives.

The priority of the magic match here being bumped to 60 seems to
indicate intent to make it take precedence over the parent
`audio/vnd.dts`. But we should take the parent magic into account here
as it does not "inherit" with `sub-class-of`.

As the comment for this match says "16bits HD be", accept only "16bits
core be" as the parent at least for now, not all possible parent
magics -- it would not seem consistent to have it in "14bits"
variants, or the "16bits core le" one. The test case we have for this
is one matching "16bits core be".

I failed to include the test files in the list in
238f20f8, and unfortunately can no
longer remember their origin. I likely took an existing one from the
test suite and converted from it, but the details and tools used escape
me.

My editor keeps adding it (which is nice), but I need to remove it
manually all the time not to include it as unrelated whitespace in other
commits (which is not). Just add it.

If the user has no program installed that handles .url files, the file
should open in a text editor so that the user can copy and paste the

JSON Schema files are distinguished from other JSON files by a "$schema"
property which is typically at the beginning of the file.

Stub files are files containing type hints, they are
written in normal Python 3 syntax, but
