ogg dev - Jun 2008 - How Ogg mappings translate into the codecs parameter in Ogg media types

I agree - we should use only hex or octal, but not mixed.

Cheers,
Silvia.

Seems nobody else has an opinion on the subject.  I leave it at your
criteria to choose one of them (hex/octal) and patch the table
accordingly.

I third the motion :-)

K.

If you want another opinion, the table currently lists the magic  
strings in the format they're given in their respective  
specifications, so it may be less confusing to have the mix of escape  
styles. If anyone needs to check and you've converted them, they'll  
have to convert back. And if octal<->hex was a trivial operation for  
most people, we wouldn't be having this conversation.
