The current prose
"
Special Exception Note: For CTTs where there are No Spoken Languages or No Subtitles, the proper DCNC code is XX. This code is only for usage within the CTT. The absence of the <Language> element where optional shall denote there is no spoken or written language.
"
Per SMPTE discussion : SMPTE/rdd52#12, the <Language> for MainAudio asset tends to be disallowed, replaced by MCA.
I suggest the prose to be updated by including the absence on a <RFC5646SpokenLanguage> in the <SoundfieldGroupLabelSubDescriptor>, when MCA are used.
