Access Style libraries for AI generation

[michox]

I'd like to build a small AI bot, that generates XML code for diagrams. This is easy enough for simple diagrams, but I'd like it to be able to search and select from the advanced libraries. Here, the style codes are rather arbitrary, and the code is not connected at all to the meaning, they seem to be just enumerated. Is it somehow possible to access the source code of those libraries or is there a more specific documentation that maps style code with e.g. the hover tool tip of the item?
