Getting xref to work against my own api docs

[blowdart]

I'm having a heck of a time trying to get xrefs working from docs to my own apis, generated as part of the docfx project.

My docfx.json

I'm pulling in the csprojs via

    "metadata": [
        {
            "src": [
                {
                    "src": "../src",
                    "files": [
                        "**/*.csproj"
                    ]
                }
            ],
            "dest": "api",
            "outputFormat": "apiPage"
        }
    ],

With this I expected to be able to

[idunno.AtProto.Cid](xref:idunno.AtProto.Cid)

but when I compile the project I get errors,

Applying templates to 343 model(s)...
G:\idunno.Bluesky\docs\docs\xreftest.md: warning UidNotFound: 3 invalid cross reference(s) "idunno.AtProto.Cid", "<xref:idunno.AtProto.Cid>", "idunno.AtProto.Cid.ToString()".
G:\idunno.Bluesky\docs\docs\xreftest.md: Details for invalid cross reference(s): "idunno.AtProto.Cid" in line 5, "<xref:idunno.AtProto.Cid>" in line 9, "idunno.AtProto.Cid.ToString()" in line 11
XRef map exported.

and the xrefs just don't work, links end up rendering to the xref link rather than an http link.

I've tried the various syntaxes,

[idunno.AtProto.Cid](xref:idunno.AtProto.Cid)

@idunno.AtProto.Cid maybe?

<xref:idunno.AtProto.Cid> maybe?

[idunno.AtProto.Cid.ToString()](xref:idunno.AtProto.Cid.ToString())

and nothing works for me.

What am I doing wrong?

Currently xref link to API page is not supported when using "outputFormat": "apiPage".

Oh fudge. Well at least it's not me then.
