Look, there isn't really a "test" case. I'm just asking if this feature is available.
The docs just say that & exports to &amp; in HTML export and \$ in latex export. 
I'm asking if there's a way to disable that feature on a case-by-case basis i.e., 
I want & to export to & in HTML export for some situations. Hope that's clear enough.

Here's a test macro:

#+MACRO: ANG @<math>@<mrow>@<mo>&x2220;@</mo>@<mi>$1@</mi>@</mrow>@/math>

This should be "angle $1". The MATML snippet works fine in a HTML file in firefox linux but the macro does not. I get this in the HTML export:

<math> <mo> &amp; #x2220; </mo> <mi> ... </mi> </mrow> </math>

& gets incorrectly converted to &amp;
