<br>
You are absolutely right, those are real errors in the spec. Looks like they
were introduced in the process of converting from our initial Word specs. I
verified data structures against original document as well as actual code
reading MATH table. To make it easier for Vlad to make corrections in the spec,
I'll repeat all correction here:<br>
<br>
1. In MathConstants table: Fields DelimitedSubFormulaMinHeight and
DisplayOperatorMinHeight should be USHORT instead of signed SHORT</span></p><p class="MsoNormal" style="margin: 0in 0in 0pt;"><span lang="EN" style='font-size: 12pt; mso-ansi-language: EN; mso-bidi-font-family: "Segoe UI";'><br>
2. In MathConstants table, StretchStackGapBelowMin field of type
MathValueRecord should be added after StretchStackGapAboveMin with following
description: "</span><span lang="EN" style="font-size: 12pt; mso-ansi-language: EN; mso-bidi-font-family: Arial;">Minimum gap between the ink of the stretched
element, and the (ink) top of the element below. Suggested:
LowerLimitGapMin."</span></p><span lang="EN" style="font-size: 12pt; mso-ansi-language: EN; mso-bidi-font-family: Arial;"></span><p class="MsoNormal" style="margin: 0in 0in 0pt;"><span lang="EN" style='font-size: 12pt; mso-ansi-language: EN; mso-bidi-font-family: "Segoe UI";'><br>
