<xsl:variable name="queryParams"
  select="tokenize($URL_query_string, '&amp;')"/>

<xsl:variable name="approvedParams"
  select="for $p in queryParams[startsWith(., 'approved=')]
          return subtring-after($p, 'approved=')"/> 

<xsl:value-of select="concat('(', string-join($approvedParams, ','), ')')

No, because the values aren't integers until you convert them to integers.

You can use "castable as xs:integer" to test whether they are capable of
being so converted.
