New annotation / tags.

Overview: We have a unique need to add a new annotation / tag to Apex docs. I think it would be good for the community at large, and rather than forking apex docs, I wanted to ask if you'd be ok with a PR? and if you could help me orient myself to it. I'm happy to do the work.

Specifics: We work in a highly regulated org. There are certain apex actions / settings and or configurations that we have to Justify the use of. For instance, we have to provide justification for the use of any query or DML that doesn't use 'WITH USER_MODE'. We would like to introduce a new, optional, tag @justification similar to @description. The key is, we need the doc generator to honor and publish that justification in the output.

Thoughts?
