<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> My question is really about HTML. I am
implementing an open source defect tracking system called Roundup (a set of
Python modules), and noticed that it uses TAL. However, I looked all
through the Roundup and Python HTML and did not find a namespace
declaration. Isn’t one required? This from
(http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixC.stx):<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The prefix identifies the language, and must be introduced
by an XML namespace declaration in XML and XHTML documents, like this:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>
xmlns:ns="http://language.creator.com/namespaces/MyAttributeLanguage<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>I realize that the statement above
mentions XHTML but not HTML, implying that non-well-formed HTML does not
require the declaration. But in the absence of the declaration, how does
HTML know how to handle a TAL statement attribute? Why wouldn’t it
balk as soon as it sees the tal: prefix?<o:p></o:p></span></font></p>
