Yes, you can do this if you aren't using FOP.  See this reference:

You can put choose statements inside an xsl:attribute inside an 
xsl:attribute-set, and select based on self::screen or 
self::programlisting.  Here is an example from another part of my book:

<xsl:attribute-set name="formal.title.properties">
  <xsl:attribute name="text-align">
      <xsl:when test="self::table">center</xsl:when>
You have to do this with each property.  Be sure to include an 
xsl:otherwise so you don't leave an empty attribute.
