[mpeg-OTspec] RE: CFR corrigendum (was: Good news about CFR (aka ISO/IEC 14496-28:2012)

[Levantovsky, Vladimir]

Thank you Ken.
I believe you're right and we need to allow both 'ComponentDef' and 'LanguagePreferredList' elements as children of 'Components' be present at the same time but let's confirm this with Apple.

Once confirmed, I will prepare a draft input contribution for corrigendum.

Thank you,
Vlad
