NOT be matched by a wildcard in the PATHPATTERN.
+ Note: As each PATHPATTERN describes the paths that a delegated role is

Some example PATHPATTERNs and expected matches:
* a PATHPATTERN of `"targets/*.tgz"` would match file paths
`"targets/foo.tgz"` and `"targets/bar.tgz"`, but not `"targets/foo.txt"`.
