Build reference pages in a wiki

We have a list of around 200 docbook-entries that need to be converted to a wiki-format. With tools like Pandoc and some scripts, we think this is very doable. The problem is that each entry has different versions, and the differences need to be merged such that these lines are marked with "new in version X" or "deprecated in version X". For example. entry1_v1: parameter 1, 2 and 3 return-code A, B entry1_v2: parameter 1, 2, 3 and 4 return-code A, B, C entry1_merged: parameter 1, 2, 3 and 4* return-code A, B, C* *) new in version 2. We think a lot can be automated, but that still manual work needs to be done to get clean version - you know, the exceptions. One of the options is to use XSLT to do the merge, but that's just an idea. The whole project is for an open standard API, which we strongly support. If we're happy with your work, there will be follow-up projects.
