[Zope] keyword args where the keyword is a variable in dtml

[Albert Boulanger]

I want to change the following dtml which works:

<!--#var expr=getPropertyType('default') -->
<!--#if "hasProperty('lastValue')"-->
<!--#call "manage_changeProperties(lastValue=newval)"-->
<!--#else-->
<!--#var expr=getPropertyType('default') -->
<!--#call
"manage_addProperty('lastValue',newval,getPropertyType('default'))"-->
<!--#/if-->

to somethiong where 'lastValue' is a parameter.

The problem is manage_changeProperties(lastValue=newval) takes keyword
args and I am not sure how to prepare to pass the args if lastValue is
the value of some variable.
