+<p class=note>This concept is used to validate [=/element=] [=Element/local names=], when
+constructed by DOM APIs. The intention is to allow any name that is possible to construct using the
+HTML parser (the branch where the first [=code point=] is an [=ASCII alpha=]), plus some additional
+possibilities. For those additional possibilities, the ASCII range is restricted for historical
+reasons, but beyond ASCII anything is allowed.

+ <p>The following JavaScript-compatible regular expression is an implementation of the above
+ definition:
+
+ <pre class=lang-javascript>
+  /^(?:[A-Za-z][^\0\t\n\f\r\u0020/>]*)|(?:[:_\u0080-\u{10FFFF}][A-Za-z0-9-.:_\u0080-\u{10FFFF}]*)$/u

Thanks for making this regex! I think it's very useful for checking against my test and implementation.

I'm not sure that this regex is correct, or maybe my test and implementation is wrong, or maybe I'm using the regex incorrectly. Here is a test that I derived from the WPT I'm writing which shows which test cases I don't think match up: https://codepen.io/jarhar/pen/azzMgMP
