How to differentiate Mandatory and optional attributes at runtime?

I have created a poller component like this:

FilePoller :
'File::Poller' name=ID '{'
(
'directory' directory=STRING
('autoCreateDirectory' autoCreateDirectory=Boolean)?
)
'}';

Here, directory is mandatory and autoCreateDirectory is optional.

For the user, I want to provide different icons for content-assist.
I am currently hardcoding the attribute names in proposalprovider and giving different icons.

Is there any way to know it during runtime?

Don't know if what you are asking is how to know what is stated in the
grammar - if so the GrammarAccess gives you access to just about everything.
