This is a fork of Go Networking.
It augments the HTML parser with ParseOptionCustomElements, an API to register non-standard element names with the parser.
This API can be used to parse HTML files augmented with non-standard elements, e.g. for embedding some kind of metalanguage.
It is mainly used by askew to parse its component and site definitions.
All other code is not touched and should not be used. It is merely kept around to facilitate updates from upstream.
