The current DOM standard says DocumentType.internalSubset should be removed:
https://dom.spec.whatwg.org/#dom-documenttype-internalsubset It looks like Chrome has already removed it: https://code.google.com/p/chromium/issues/detail?id=272096 http://codereview.chromium.org/282823004 It seems the change stuck, because my Chrome 45 doesn't support it. This suggests it's safe to remove. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
