Yes, you can:

  d[i] = <esql:get-double><esql:column><xsp:expr>i</xsp:expr></esql:column></esql:get-double>

BTW xsp:attribute adds an attribute to the output stream while you
want to add an attribute to a logicsheet tag. Most - but not all -
follow the pattern <prefix:param name="foo">value</prefix:param>
Note that the logicsheet in question - and the tag in particular -
needs to support dynamic values. Unfortunately, only an inspection of
the xsl reveals what is supported and what isn't.
