Chris@102: \par Formal definition:
Chris@102: The multi linestring concept is defined as following:
Chris@102: - there must be a specialization of traits::tag defining multi_linestring_tag as
Chris@102:   type
Chris@102: - it must behave like a Boost.Range
Chris@102: - its range value must fulfil the Linestring concept
