[boost] Collection Concept

Hi,

I have recently discovered the specification of the collection concept in the boost repository.
(boost/libs/utility/Collection.html)
I found it very interesting in connection to string_algo library and especially container_traits.

It almost precisely models the concept which is widely used there, but has not been specified
to concrete details yet. However it was requested during the review as a very important.

The required concept should reflect the properties provided by container_traits. Collection
is almost perfect, but there is one thing, that is problematic.

There are important data types supported by container_traits, that cannot provide swap() functionality.
Therefore I would need to remove swap from collection specification to use it.

My questions are:
1. Is there a plan to add Collection concept to the ConceptCheck library?
2. Is the "swap" requirement so important, that it eventualy couldn't be relaxed?

Regards,

Pavol
