I wasn't making fun of you.

Sorry, it's "structure" you want to use.

<tal:replace="structure <some tag or other>">

Now, if you are going to generate some complex tag then you are best  
of doing this in a PythonScript and returning the string to the  
template. However, I do not think that is the way to want you want as  
I this only makes sense for extremely dynamic content. In my view  
it's better to use standard tags.

Your source is virtually impenetrable to me which I think is a guide  
to it being wrong.

<span tal:define="r record/name; id record/task_id; mylt
string:'<'; mygt string:'>';"
            tal:replace="string:${mylt}option label='${r}'
value='${id}'${mygt}${r}${mylt}/option${mygt}"></span>

<option tal:attributes="label record/name; value record/task"  
content="record/value"></option>

No formatting required at all. At least I think that's what you want!
