An empty message can be a macro, that contains many things,
\define onemptymessage()
{empty message code here}
\end
<$list filter="""[<variable>length[]match[9]then[short]else[long]]"""
variable="type" emptyMessage=<<onemptymessage>> />
{full code here}
</$list>
It can even look like this
<$list filter="""[<variable>length[]match[9]then[short]else[long]]"""
variable="type"
emptyMessage="""
{empty message code here}
"""/>
{full code here}
</$list>
Extending Saq suggestion; I expect this to work (untested today)
[<variable>length[]match[9]then<shortval>else<longval>]
The only limitation being macros cant be passed variables, complex macrs
may need their result wikified before using in a filter
Remember as well is all you want to know is is it long or short this will do
{{{[<variable>length[]match[9]then[short]else[long]]}}
