ISSUE-63: tts:dynamicFlow - need to clarify meaning of "logical content position" in B.2

tts:dynamicFlow - need to clarify meaning of "logical content position" in B.2

State:
CLOSED
Product:
TTML 1.0
Raised by:
Glenn Adams
Opened on:
2009-04-23
Description:
by "logical content position" I had in mind a numbered, logical
sequence of content characters that correspond to the glyphs associated with
glyph areas; the logical position is based on the input character string
order, and not on the resulting (visual) glyph (display) order, so this
sequence is determined prior to bidi processing; I will add normative text
that makes this definition clear; N.B., the notion of logical order versus
visual (or presentation) order is discussed in some detail in [1];
