Domain labels aren't defined, but let's suppose they are actually strings. So a host is a string in the form of an ordered list of strings. That doesn't make sense. :-) Various algorithms in the spec seem to switch between treating "host" as a string and as a list of strings. 96776 1 annevk 2013-11-25 15:00:48 +0000 https://github.com/whatwg/url/commit/232157a284157ca60d40dd391ef5ae88f79a9e9a I'm still a bit torn whether to define the components of a URL as byte sequences or strings. API-wise the latter is easier, though it seems they are really byte sequences, including domain labels. Though domain labels also have a (Unicode) string variant. 98256 2 annevk 2014-01-10 11:41:57 +0000 Marking FIXED as the issue raised here was resolved.
