It's fairly Zope-heavy, though.

I can understand that.  I've been thinking more and more about the need 
for an escaping convention.

It's part of TAL, since it is only meaningful for 'content' and 
'replace' and tells those statements *not* to do something they would 
otherwise do.  Example:

<p tal:define="line string:&lt;hr&gt;">
One <tal:line replace="line" /> Two
<tal:line replace="structure line" /> Three
</p>

...becomes:

<p>
One &lt;hr&gt; Two
<hr> Three
</p>

Note that 'attributes' can't have 'structure', because XML attributes 
must be escaped.
