Thanks everyone for your input. It sounds like the following should be acceptable:
1. A_DTS is used for and DTS content that contains a core substream. It might be helpful to explicitly state this in the specification, e.g. "A_DTS supports DTS, DTS-ES, DTS-96/26, DTS-HD High Resolution Audio and DTS-HD Master Audio".
2. A_DTS/EXPRESS will be used for DTS Express (a.k.a. LBR) audio streams
3. A_DTS/LOSSLESS will be used for DTS Lossless audio that does not have a core substream
Is there any other component of the MKV spec that needs to be modified to support the two new applications of DTS codecs?
Is there anything else that needs to be taken into consideration?

I think it's better not to break what we have today. But we could mark
HD and non-HD with the codec private. It should be discarded by
existing players adn DTS decoders don't expect to be passed external
codec data. And it would be possible to spot which one are actually HD
without breaking anything. (non-HD ones will simply have no codec
private data set).
