MicrosyntaxDescriptions

From WHATWG Wiki

The purpose of this page is to enable collaborative creation of brief advisory text for each HTML5 microsyntax so that when an attribute value does not conform to a given microsyntax, a validator can display the advisory text about the syntax to guide the author to fix the value. Note that like the rest of this wiki, editing requires you to agree to release your contributions under the MIT license (see wiki footer). Copying text from the WHATWG version of HTML 5 is OK.

Note that some formats pertain to Web Forms 2.0 (e.g. DatetimeLocal is datetime-local).

Language

An RFC 4646 language tag consists of hyphen-separated ASCII-alphanumeric subtags. There is a primary tag identifying a natural language by its shortest ISO 639 language code (e.g. en for English) and zero or more additional subtags adding precision. The most common additional subtag type is a region subtag which most commonly is a two-letter ISO 3166 country code (e.g. GB for the United Kingdom). IANA maintains a registry of permissible subtags.
