Brace matches path with REST-full resources URI in brace form.
e.g., "/foo/v1/bar/v2" will map to "/{foo}/{bar}" form,
while the value of "foo" and "bar" are "v1" and "v2", respectively.
Colon matches path with REST-full resources URI in perfix colon form.
e.g., "/foo/v1/bar/v2" will map to "/:foo/:bar" form,
while the value of "foo" and "bar" are "v1" and "v2", respectively.
Wildcard matches paths with wildcard form.
E.g., "/foo/v1/bar/v2" will match the form "/foo/*/bar/*",
and "/foo/v1/v2/bar" will match the form "/foo/*/*/bar", but
will not match "/foo/*/bar".
