Link in raw HTML do not throw errors.
<a href="custom://link">custom://link</a>

Only JS location.href
<span onclick="location.href='custom://link'">custom://link</span>

There's no way to throw an exception from the <a href>, since that's not in script.

You presumably want the browser to silently do nothing instead.  It's not clear to me why this would be better than telling the calling script that the load is flatly not possible, but in any case it needs spec work.

The spec [1] requires raising a SYNTAX_ERR if resolving the URL is unsuccessful. However, thanks to the URI people, the resolving algorithm is useless ATM.

So setting href invokes http://url.spec.whatwg.org/#dom-url-href which invokes stuff from http://www.whatwg.org/specs/web-apps/current-work/multipage/history.html#location which throws an exception. I guess the question is whether that should be caught or not.

This is per the standard.
