document technologies for "Framework 7"

QAWG,

This is an interesting reference, for those interested in document 
technologies (markup language options), as we ponder how to evolve the 
Framework 7 family.

 From the summary description -- and I haven't looked at the system in 
detail -- it seems to do a lot of nice things for document presentation and 
management, but it is unclear whether/how it supports or allows for 
extensions (e.g., <div class="">, etc) for granular structuring of the 
document (e.g., test assertions).
