[mkgmap-dev] Non way element X in multipolygon Y

I get a lot of warnings of the form "Non way element X in multipolygon Y" (e.g. Non way element 247735163 in multipolygon 339577) in which X is a correct "admin_centre" node of a boundary multipolygon relation. Would it be possible to detect "admin_centre" tag when the MP is processed to avoid this warnings in the log?
