[Zope] ZPT Equivalent of <dtml-var title_or_id>

[beno]

I thought this would be easy but apparently it's not.
The sample ZPT sheet in the 2.6 distro has this line of code:

<title tal:content="template/title">The Title</title>

Unfortunately, that doesn't render a thing! So, why is it there?? Someone 
suggested this:

<title tal:content="here/title">The Title</title>

which sounded like a good idea, but no cigar. What I want is the ZPT 
equivalent of this:

<dtml-var title_or_id>

Does it exist??
TIA,
