Here are some links with information about CSA

icm_0nsj.asp
http://www.boscarol.com/pages/cms_eng/076-csa.html

TN5604.DeviceN_Color.pdf (page 19)
http://www.adobe.com/support/techguides/color/colormanagement/
cmssol.html
and many more.
But here I was wrong, true is the following:
CRD = Color Rendering Dictionary (ICC B2A...)
CSA = Color Space Array (ICC A2B...)
I'm not a programmer for postscript but that's what everybody's talking
about (Adobe, Harlequin, Microsoft, Apple, Gretag, ...)
I don't think that they all write about something that isn't existing.
But who knows :-)

Nope, no such thing as a CSA. The equivalence is:
ICC input (A2B) = PostScript CSD, AKA "CIE based color spaces"
ICC output (B2A) = PostScript CRD
Level 2 PS supports 1 or 3 channel spaces (CIEBasedA and CIEBasedABC),
which
are equation based (Roughly equivalent to ICC matrix profiles), while
PS level 3 introduces 3 and 4 channel spaces that allow table lookups
(CIEBasedDEF
ad CIEBasedDEFG) which are roughly equivalent to ICC clut based
profiles.
