@version will _not_ give you that ability, as pointed out by Ian.  What
@version will do is let you say "if you think you support cssX, process
this block".  A UA can then proceed to process that block even if it
does not have full support for all the declarations in it but thinks its
cssX support is good enough.

What you really want is a "treat as block and use or discard together"
grouping feature, which seems to be a much more reasonable approach than
@version.
