Indeed. I should have known better. Temporary attack of brain weakness, I suppose. For those who want to see for themselves, the minimal example below will do.

dr. Hans van der Meer

% test character entity.
\startxmlsetups demo:entity
	\xmlsetsetup{#1}{root}{demo:entity:*}
\stopxmlsetups
\xmlregisterdocumentsetup{demo}{demo:entity}
\startxmlsetups demo:entity:root
	\blank Start test:\crlf
	flushing: \xmlflush{#1}\crlf
	End test\blank
\stopxmlsetups
\startbuffer[demo]
<?xml version="1.0" encoding="UTF-8"?>
<root>amp = &amp; and #38 = &#38;</root>
\stopbuffer
\starttext
\currentdate-\currenttime\quad\ConTeXt-version=\contextversion\blank
{\bf Testing use of character entities}\blank
These should produce the same result: \type{&amp;} and \type{&#038;} and indeed they do.\blank
\xmlprocessbuffer{demo}{demo}{}\blank
\stoptext
