[Zope] passing positional paramaters

[Cliff Ford]

It is not clear to me why you would pass None parameters to a select 
query. Typically your query would have named arguments (name and 
doclang) like this:

select * from yourTable where name=<dtml-sqlvar name type=string>
and doclang=<dtml-sqlvar doclang type=string>

Leave out the last line if you don't want to select and doclang.

Then call the query like this:

<dtml-in expr="gettransdoc(name=name,doclang=doclang)">
<dtml-var ordering> <dtml-var content><br>
</dtml-in>
