Doxia rejects/rewrites intentional relative http: link in APT

I wrote:

{{{http:./jdd/index.html}A Link}}

Because I know that there is going to be such a page by the time my output is deployed. I expected the http: to cause Doxia to 'butt out'. Instead, I get:

[WARNING] [APT Parser] Modified invalid link: 'http:./jdd/index.html' to '#http:.jddindex.html'
[WARNING] [APT Parser] Ambiguous link: 'http:./jdd/index.html'. If this is a local link, prepend "./"!

Notice that I DID prepend ./. Taking out the ./ doesn't help.
