ISSUE-114: HTML5 content model for @href/@src coerces values to URLs

HTML5 @href as URL

HTML5 content model for @href/@src coerces values to URLs

State:

CLOSED

Product:

RDFa 1.1 in HTML5

Raised by:

Opened on:

Description:

HTML5 has DOM access rules for accessing @href/@src values (in addition to others) in "Resolve URLs" [1]. The affect of these is to both require that relative URLs take into consideration xml:base, and that IRI paths are turned into URIs using percent encoding. (Note xml:base is not allowed in HTML5 docs, but it would be in XHTML5).

Step 6 normalizes any _host_ component to UTF-8 and then performs a IDNA ToASCII algorithm [2].

Step 7 normalizes any _path_ component that is not ASCII with the percent-encoded equivalent.

The result of both these steps is that IRIs may be converted to URIs. This means that @href and @src may not safely be used with IRIs that are not URIs. There is no such requirement on DOM access for @about, @typeof or @resource, so these may safely be used for representing IRIs, but may have different relative-IRI resolution algorithms imposed.
