I want to create properly linked documentation pages dedicated to specific messages issued by my own functions inside a package, similar to those for messages of built-in functions like Integrate below:

Integrate[x,2]

Integrate::ilim : Invalid integration variable or limit(s) in 2. >>

Here, the ">>" links not to the Integrate help page, but to a page specific to the message Integrate::ilim:

How do I create such a page in Workbench? And how should one properly link the Messages to their appropriate pages?
