This *should* be fixed now in the CVS trunk and 2.7 branch.  Interested parties please test and comment.

I currently discovered this behaviour on a HEAD checkout from 2003/07/14. 

Is it possible this bug slipped in again? Also in XML mode i discovered that the attributes are presented after character reference substitution (happens only in the attributes, not the rest of the document).

So this happens to an attribute "string:ä":

            Macro-Expansion On    |    Macro-Expansion Off

XML-Mode    "string:ä"            |    "string:ä":     

HTML-Mode   "string:ä"   |    "string:ä":


I tried to locate it further. It happens somewhere in the
interpret() method from the TALInterpreter.

Fixed in CVS trunk by not escaping ampersands in attributes that start off a syntactically valid character entity.  Note that this includes semantic nonsense such as "&blah;" and "�" as well as valid entities such as "á" and "d".

ZPT escapes the ampersand of character entities
in attributes. They should not be escaped since
they are legal HTML and needed to make accented
characters, for example in <img alt="">

To check this, put the following line in a Template
and view the result.

<span alt="&aacute;"></span>
