Title: service container parameters can also be arrays. added example

i was using arrays in yml configurations and converting that to xml. with some trial and error figured out how its supposed to work from the xml schema definition.

btw, would be nice if the xml parser would complain about child elements in non-collection tags. currently it just gets the whitespace between the tags when i omit the type="collection" attribute.
