[svgwg] Specifying processing model and algorithm for `ping` and `referrerPolicy` in SVG `a` element (#1029)

goldenboy777 has just created a new issue for https://github.com/w3c/svgwg:

== Specifying processing model and algorithm for `ping` and `referrerPolicy` in SVG `a` element ==
Chromium is planning to support the hrefLang, type, ping, and referrerPolicy attributes for SVGAElement ([Intent to Ship](https://chromestatus.com/feature/5140707648077824?gate=6224522713890816)), in alignment with the [SVG2 specification](https://svgwg.org/svg2-draft/linking.html#InterfaceSVGAElement).

Following the links related to referrerPolicy in the spec ([reference](https://svgwg.org/svg2-draft/linking.html#AElementReferrerpolicyAttribute)), it states:

>These attributes further describe the targetted resource and its relationship to the current document. Allowed values and meaning are [as defined for the a element in HTML](https://html.spec.whatwg.org/multipage/text-level-semantics.html#the-a-element).

While the expected behaviour of these attributes should mirror that of HTML `a` elements, there is ambiguity regarding the processing model and algorithms, particularly for `ping` and `referrerPolicy`. 
This concern has been raised by Chromium API owners and echoed by WebKit contributors ([signal discussion](https://github.com/WebKit/standards-positions/issues/566)).

Should the SVG2.0, be updated to include this information explicitly? Should relevant links corresponding to processing model and algorithm of HTMLAnchorElement be given for that?
