Christian Stefan wrote me to point out that the OOXML specification published by ECMA uses 1.5 line spacing, while OASIS uses single spacing. I quote from his message:
ODF 722 pages
SVG 719
MathML 665
XForms 152 (converted from html using winword, ymmv)
XLink 36 (converted from html using winword, ymmv)
SMIL 537 (converted from html using winword, ymmv)
OpenFormula 371

3,202
Now I'm still missing some standards that would add severall hundred
pages and changing line spacing to 1.5 will bring me near the 6000
pages mark I guess. This is not very surprising (at least for me)
since both standards try to solve very similar problems with nearly
equal complexity.
Zkráceně 3202x1,5=4803 stránek, což se už tak moc neliší od 6000 stránek ooxml.
