Many of the entry headers in the propdef tables (e.g., "Value", "Computed value", "Animatable", "Canonical order") should be hyperlinks to the specification that defines what those entries mean.

Ideally, bikeshed should have a way for a specification to declare that it is defining one of those headers, and then other specifications that use the header would link to that definition.

Alternatively bikeshed could just hardcode what they link to; it's not something we'd need to change all that often.
