I was quoting the draft, 
http://www.w3.org/TR/2012/WD-vocab-data-cube-20120405/.  (My bad, the 
"SDMX and related materials" is a title in the current draft, should 
have so indicated.)

No and that was why I asked.

 From above (and the draft):

I don't know how to evaluate: "...available separately for use along 
with..."

Could be a non-normative (informative) reference to helpful material.

Thanks, see comments above.

Sure, but then informative references, in a note for example.

Hope you are having a great day!
