[The following is extracted from the liaison received from SMPTE at https://lists.w3.org/Archives/Member/w3c-archive/2012Sep/0214.html]

See Section 6.4.9 at ST 428-7 and Section 8.2.9 at TTML.

It shall be possible to express tts:fontSize dimensions as a percentage of the root container dimensions.

Note: this allows the same TTML document to be used to burn-in subtitles on a range of container sizes, e.g. 1080p, 2K, 4K, without modifying tts:fontSize for each output.
