[DJW:]  No.  Attribute CDATA is not the same as CDATA
sections in as much as entities are expanded, but it is
still not parsed for elements and directives.  The syntax
definition permits:

1) entity references;
2) any character except the character used to quote the string,
   <, and &.

It doesn't recgnize anything else.  Note that section 4.4.2 forbids
sneaking mark-up into parameters using general entities.
