[DAS] maxbins in DAS1.6?

[Andy Jenkinson]

Yep, it should now be a little easier to tell. Also, the 1.6-compliant  
version of ProServer will only pass the parameter through to a  
SourceAdaptor if the adaptor declares support for it. This is one of  
the ways I hope to encourage compliance with the parts of the spec  
that usually get neglected - i.e. metadata. Ideally clients would work  
on the same principle, i.e. if maxbins is not declared as a  
capability, it won't be sent in the request. More tolerant clients  
tend to result in inconsistent implementations in servers. Another way  
is that the registry will check for capabilities that are supported  
but not declared. Hopefully we can establish both incentive and  
necessity to describe sources accurately.

Regarding the question of how the registry checks maxbins, Jonathan  
will have to answer that one.

Cheers,
Andy
