Re: Docs: Create table description for constraints markup fix and label tweaks

Hi David,

I reviewed both patches on the latest HEAD.

0001: SGML nesting fix applied and verified - make html
builds successfully with the corrected element nesting
for UNIQUE and PRIMARY KEY.

0002: The six "variant" label changes look good and should
help avoid the confusion reported on -general.

Looks good to me.

Regards,
Dapeng Wang
