The ‘xsl:value-of’ elements are just going to put the result of the
expression ‘@floatstyle = 'none'’ in the output document, i.e. ‘true’
if ‘@floatstyle’ is ‘none’, ‘false’ otherwise.  I /think/ you can
achieve the preprocessing you actually want using variables.  Here’s
one (untested) possible solution:

,----
| <xsl:template match="*[@floatstyle = 'before']">
|   <xsl:variable name="preprocessed">
|     <xsl:copy>
|       <xsl:attribute name="floatstyle">none</xsl:attribute>
|       <xsl:apply-templates select="@*[not(local-name() =
'floatstyle')] | node()"/>
|     </xsl:copy>
|   </xsl:variable>
|
|   <xsl:choose>
|     <xsl:when test="column.count.body = '1'">
|       <xsl:apply-templates select="$preprocessed"/>
|     </xsl:when>
|     <xsl:otherwise><xsl:apply-imports/></xsl:otherwise>
|   </xsl:choose>
| </xsl:template>

Hope this doesn’t break anything. ;-)
