* Sanitizer: dev.w3.org/html5/spec-preview Follows-up8e8b15afc6. Use stable reference to www.w3.org/TR/html5 instead (currently from October 2014) instead of an old preview branch from 2012. * parserTests: dev.w3.org/html5 Follows-up959aa336a1. Url is now a dead end. Replaced with link to a draft from around that time. The relevant section no longer exists in the curent spec as it got split off into a separate spec. Maybe this one: https://url.spec.whatwg.org/#percent-encoded-bytes * Parser, HTMLIntField: dev.w3.org/html5 Use stable reference to www.w3.org/TR/html5 instead. * HTMLFloatField.php: dev.w3.org/html5 Url is now a dead end. Draft from around that time: http://www.w3.org/TR/2011/WD-html5-20110525/common-microsyntaxes.html#real-numbers The section "Real numbers" no longer exists in the current spec, but the Infrastructure chapter has a section on floating point numbers that describes the same sequence now.
