using an isDate() on the argument before it gets passed in?
<cfif isDate(myVar)>
#DateTime.DateOutput(myVar)#
<cfelse>
foo
</cfif>
or sure...you could change the type attribute of the cfargument to a
string and do the validation in the function itself.
not sure which would be considered more "proper" :)

This works fine, except it doesn't accept an empty myDateTime.
So I suppose I need to change type="date" to type="string".
But then I'll need to verify that myDateTime is either "" or a valid date.
