Ability to create references to to step definition, tag, and feature

[burtlo]

This is maybe already supported, but haven't found a way how to do
it. If I want to reference another step or tag or feature within
cucumber documentation, how can I do it? Let's look at the example:

#
# @see #Step::other_step
# @see #Tag::@web
# @see #Feature::"Ajax support feature"
# Look at {Sign_in_step this} step for more info about signing
# {Feature::"Login feature for guests" This} feature is ...

• those proposals are only my guessing, not sure if that is the best
  way, how to implement it.
• it would be awesome to use this references either in feature/scenario
  scope or in step definitions or to be as generous as possible - wherever
• even from helper ruby libraries, to be able but reference, where such
  method has been used:

# ...
# @note This method is use in {Step::"Some Sign In Step"}
#
def sign_in
...
end
