Issue-201 Open How to specify aspect ratio to understand positioning that may apply for display or video.

Any progress on open Issues:
ISSUE-156 semantics of missing #feature OPEN semantics of missing #feature... (Action-148 Glenn) Draft text for 2 resolutions: RESOLVED: in 1.1, add value of "prohibited" for feature definitions, also add attribute "disposition" with values "error" and "ignore" and RESOLVED: in SE, add text indicating that absence of a feature in profile means same as "optional". [on Glenn Adams - due 2013-02-28].
ISSUE-157 transformation profile OPEN transformation profile [Action-147 Glenn] Create definitions for presentation and transformation in Section 2.2 to handle Issue-157.
ISSUE-179 px measure OPEN Interpreting the pixel measure Some properties need clarification (Action-149 Glenn) Review CSS pixels and SVG to suggest a resolution to Issue-179. [on Glenn Adams - due 2013-02-28].
Issue-163 Clarify use of cell units in certain properties OPEN (Action-148 Glenn) Clarify cell units as Sean specified as follows: .Style properties that operate in both the horizontal and vertical direction, such as border, outline thickness etc. may be specified using a single value which is based on the cell unit. When the cell is non-square, the computed value is calculated based on the height of the cell. For example: Given a root extent of 852px 480px and a ttp:cellResolution="30 20"; then in pixels the horizontal cell size is : 852/30 = 28.4 pixels, in the vertical 480/20 = 24 pixels. The relative unit to be used is 28.4px
ISSUE-170 5.2-para8 OPEN Section 5.2 para 8 is vague regarding optionality of specifying profile in case where profile is negotiated/determined by 'document interchange process'   
Issue indicates Glenn added text to TTML 1.0 SE. Delete, "then the DFXP Transformation profile applies"? Take further comments.
