Comments on MathML entities

Dear Committee,

I have worked on the translation of the Elsevier Science character
grid (http://support.sciencedirect.com/sgml/docs/tagbytag.pdf, Chapter
6, Elsevier Science Grid) to Unicode. I have used the STIX table and
the MathML entity files. During that task I have made a number of
observations on the MathML entity files, which I am sending you
herewith in the hope that they are useful.

heartsuit: MML 02661 = white; should be 02665 = black
hearts is not defined; should be 02665 for consistency with spades etc.

xsqcup: STIX 02A06 = n-ary, MML 02294 = normal;
xuplus: STIX 02A04 = n-ary, MML 0228E = normal;
in both cases n-ary is the right choice.
Similarly for xutri, xvee, xwedge.

els: MML 022DC is not slanted; should be 02A95.
egs: MML 022DD is not slanted; should be 02A96.

lEg: MML 022DA does not have double equal; should be 02A8B.
gEl: MML 022DB does not have double equal; should be 02A8C.

lne: MML 02268 has double equal; should be 02A87.
nle: MML 02269 has double equal; should be 02A88.

nlE: MML 02A7D-00338 does not have double equal; should be 02266-00338.
ngE: MML 02A7E-00338 does not have double equal; should be 02267-00338.

sce: MML 0227D, which is curly (≽); should be 02AB0 (cf. pre).

subE: MML 02286, which does not have double equal; should be 02AC5.
supE: MML 02287, which does not have double equal; should be 02AC6.

subnE: MML 0228A, which does not have double equal; should be 02ACB.
supnE: MML 0228B, which does not have double equal; should be 02ACC.

nsubE: MML 02288, which does not have double equal; should be 02AC5-00338.
nsupE: MML 02289, which does not have double equal; should be 02AC6-00338.

digamma: MML 003DC, which is capital; should be lc: 003DD.

epsi, straightepsilon: MML 003B5, which is curly; should be 003F5.
epsiv: MML 0025B, which is not Greek; should be 003B5.

star: MML 022C6, which is (filled) star operator; should be 02606.
