DITA 2.0 question

Hi I may be behind the curve here, but are there any plans to look at bibliography information as part of DITA 2.0?
both how it is formatted and presented in a final document, and how it is stored in source (I am thinking something like bibTex) for reuse across multiple final documents.
When I checked the 1.3 standard, the only reference I could find to storing information is <data>, which is probably fraught with difficulties unless specialised, I could go down that route, but it strikes me that if MathML is supported as part of the standard, scientific documents will follow and thence referencing galore.
