This took a while to debug. The internal representation of the namespace 
macros has changed in MkIV.

\definenamespace[whatever][...]
\definewhatever[something][key=value]

now defines a macro \whatever:something:key rather than 
\whateversomethingkey (note the extra colon). In the filter module, I had:

\getparameters[\externalfilter::namespace#1][\s!parent=\externalfilter::namespace,#2]

which fails in MkIV. To get a working solution in both MkII and MkIV I 
need:

\setupexternalfilter[#1][\s!parent=\externalfilter::namespace,#2]

@Hans and Wolfgang: Is it possible to change the internnal representation 
in mult-aux.mkii so that MkII and MkIV are consistent again?

@Hraban: Long story short, the filter module is working again. Can you 
test the dev branch from the latest git version?
