As you can see in the above link, simple cases like missing '<' at
start, repeated modifier, missing '>' at end, errors with appropriate
messages are raised.

I now updated the diff file at
https://gist.github.com/sahutd/289d2297eb83a020a6dd.
It can now ascertain which part of (whether modifier, type or detail)
is invalid.
It can also say why it is invalid(Not all reasons are covered ATM,
though it can be done quite easily. Just a matter of checking for that
condition and adding a suitable error message).
See the tests in the same diff for an example.
