Through this clause and its sub-clauses, the relationship with ISO/IEC 9541-4: Information technology - Font information interchange - Part 4: Open Font Format (dual numbered as IS 14496-22) is not adequately clear. Presumably this is because IS 14496-22 was not published until after Ecma 376 was complete.
In particular this concerns IS 9541-1 s4.1.7 OS/2 - Global Font Information Table.
Some reviewers missed that the hexadecimal values in 2.8.2.16 were standard values, and had unnecessary concerns about the use of hexadecimal numbers, in this case.
DIS Part 4 S2.8 Fonts should contain a normative reference to IS 9541-4: or 14496-22
S2.8.2.14 should clarify that Panose is used to conform with IS 9541-4: or 14496-22.
S2.8.2.16 should clarify that the values for the attributes of the <sig> element are standard values from IS 9541-4: or 14496-22

Proposed Disposition of DIS 29500 Comment AU-0013 (Modified: 2007-12-05) Agreed; instead of referencing the non-standard “OpenType” and “TrueType”, the text should reference the (now) appropriate ISO standard; the following changes will be made to rectify this: To Part 1, §3, page 5: ISO/IEC 14496-22:2007, Information technology Coding of audio-visual objects Part 22: Open Font Format.
