DTDs and Schemas

My personal opinion about what we have, will soon have, and might want in descriptors.

feature DTDs Schemas need more
content models + + no
content / attribute types weak improved yes
attribute groups via PEs + ?
archetypes via PEs + ?
open / refinable models via PEs + ?
attribute groups via PEs + ?

Conclusion: Schemas need significantly more datatype capability.

Question: Is moving to a non-backward compatible syntax, i.e. Schemas, fair to our customers?
