Undeclared general entity

in a previous post Thiago correctly explained the error 'Undeclared 
general entity "nbsp"' resulting from a missing html xmlns declaration.

however I'm still having this problem when I declare an xhtml entity 
within a page that uses a component to handle the layout, even if both 
the layout component and the page tml's declare the xhtml xmlns.:

MyPage.tml:

<html t:type="baselayout" xmlns="http://www.w3.org/1999/xhtml" 
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd">
    &nbsp;
</html>

BaseLayout.tml:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" 
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd" 
xmlns:p="tapestry:parameter">
    <t:body />
</html>

Also, another problem - if the &nbsp; is in BaseLayout.tml and not 
MyPage.tml it renders without exception, however if I view source of the 
rendered page, there is no &nbsp; instead the character it represents. I 
would expect the browser to do this conversion, not the web application.

can someone fill me in?

Regards, p.

Each of your .tml files is a complete xml file. When tapestry parses
your MyPage.tml there is no nbps entity reference defined. This is
generally found in http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd
of your DOCTYPE declaration.

Tapestry uses an xml parser to read your .tml files. It resolves the
entity references for the encoding used to render your page. Is there
a reason you want them to be rendered as entity references?
