Address #133 (missing tts:lineHeight with value not 'normal')

I'm curious: why put the tts:lineHeight attribute on body rather than region? They seem to be identical in terms of processing, but having tts:lineHeight on region would look tidier given that's where all the other style attributes are set. I suppose it avoids having to add the same tts:lineHeight attribute on all the regions when there are several in the same document instance.

Yes, it was because by putting it on body, it would cover all content in
multiple regions. If this were TTML2, we would have other options as well,
such as putting on tt or adding an initial element, in which case I would
likely use the latter (initial).
