I've been thinking about this label a bit more and, while I haven't seen that specific type before, the circles with E4 and E11 do look familiar. Those look an awful lot like ECE e-Mark certification marks.
EDIT: Just found this on the interwebs...check out the 2nd mark down (Model B) as well as the numbers to the right, ignore the mention of electromagnetic crap...

I think this helps explain the contents of your label, though does nothing to address the specifics on the regulation numbers. Apparently E4 indicates the Netherlands and E11 is the UK.
