I still am very VERY leery of having anything in comments affect the 
code in any way.

What about a compromise? Provide access to the docs but ONLY at runtime. 
That is, you will not know anything about the string at compiletime, 
just at runtime, and you can make your decisions there.

Should work for your use case.
