Re: [MMUSIC] T140: Usage of "-"fmt value in dcsa encapsulated fmtp attribute

Hi,

I intend to merge the pull request tomorrow (Thursday), so please let me know if you have any issues with it - or in general with the approach of using the sub-protocol value instead of "-" in dcsa encapsulated fmtp attribute. So far nobody has objected to such approach.

Regards,

Christer
