How can I access the comment once I get the FM3Description?

For example below I would like to access the MSEComment.

to motivate an asnwer: after we will go over all the comments (class comment and attribute comments and write them in a nice way and 

generate a documentation automatically

isWrite

<MSEProperty: #isWrite type: #Boolean>

<MSEComment: 'Write access'>

^isWrite
