Ampersand followed by semicolon in XML: possible bug?

Ampersand followed by semicolon in XML: possible bug?

[massifr]

Hello list,
I've found what it looks like a bug in XML handling in ConTeXt. Try this:

\startbuffer[test]
<text>
  <!-- with following semicolon: ampersand and semicolon are eaten -->
  <p>Me &amp; my friends; you &amp; your friends.</p>
  <!-- without following semicolon: everything ok -->
  <p>Me &amp; my friends. You &amp; your friends.</p>
  <!-- way around: place a comment after the ampersand -->
  <p>Me &amp;<!-- --> my friends; you &amp; your friends.</p>
</text>
\stopbuffer

\startxmlsetups xml:somesetups
  \xmlsetsetup{#1}{text}{xml:text}
  \xmlsetsetup{#1}{p}{xml:p}
\stopxmlsetups

\xmlregistersetup{xml:somesetups}

\startxmlsetups xml:text
  \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:p
  \xmlflush{#1}\par\blank[line]
\stopxmlsetups

\starttext
  \xmlprocessbuffer{main}{test}{}
\stoptext

In the first case, the ampersand and the following semicolon are eaten up.
I've found a way around, until the bug is fixed (if it's a bug and not my
limited knowledge of ConTeXt): put a XML comment after the ampersand,
and everything works as expected.

I've seen that the ampersand gets interpreted as HTML on the mailing list.
I'm sending the example as an attachment.

Here's a modified version to be seen on the mailing list site:
\startbuffer[test]
<text>
  <!-- with following semicolon: ampersand and semicolon are eaten -->
  <p>Me &amp;amp; my friends; you &amp;amp; your friends.</p>
  <!-- without following semicolon: everything ok -->
  <p>Me &amp;amp; my friends. You &amp;amp; your friends.</p>
  <!-- way around: place a comment after the ampersand -->
  <p>Me &amp;amp;<!-- --> my friends; you &amp;amp; your friends.</p>
</text>
\stopbuffer

\startxmlsetups xml:somesetups
  \xmlsetsetup{#1}{text}{xml:text}
  \xmlsetsetup{#1}{p}{xml:p}
\stopxmlsetups

\xmlregistersetup{xml:somesetups}

\startxmlsetups xml:text
  \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:p
  \xmlflush{#1}\par\blank[line]
\stopxmlsetups

\starttext
  \xmlprocessbuffer{main}{test}{}
\stoptext

It's a side effect of a mechanism that is enables while it shouldn't 
(relates to dealing with escaped entities). Fixed in next beta.
