You can pass a nodeset in the param, much like David's example:

   <xsl:param name="filter">
       <a>food</a>
       <a>drink</a>
   </xsl:param>

then you would need the possibility to pass a nodeset, and the nodeset 
extension to access it:
[@filter=exsl:node-set($filter)/a]. Both depend on the processor - I 
don't know if and how this is possible in yours.

If you really cannot pass a nodeset, you could always build up a search 
string something like

   <xsl:param name="filter" select="';food;drink;'"/>

and then use [contains($filter,concat(';',@filter,';'))]
