Hi,
Yes, there is a reason: you cannot apply an attribute-set with xsl:if. Many things in XSL would be simpler if you could. If you need a conditional attribute set, you must either conditionalize the value of every attribute in the attribute-set (and you still get all the attributes), or you must create an awkward xsl:choose that generates the output element either with or without the attribute-set applied, and repeat the rest of the content in both. The template with match="section" in fo/sections.xsl has such a construction for applying the different section level properties.

Subject: [docbook] Attribute Set for

Hi all,

I created some custom fo:simple-page-masters for the DocBook/4, v.1.78.1
and while adding support for draft mode to them, I wondered why the
original authors bothered with putting

 <xsl:if test="$draft.watermark.image != ''">
   <xsl:attribute name="background-image">
     <xsl:call-template name="fo-external-image">
       <xsl:with-param name="filename" select="$draft.watermark.image"/>
     </xsl:call-template>
   </xsl:attribute>
   <xsl:attribute name="background-attachment">fixed</xsl:attribute>
   <xsl:attribute name="background-repeat">no-repeat</xsl:attribute>
<xsl:attribute name="background-position-horizontal">center</xsl:attribute> <xsl:attribute name="background-position-vertical">center</xsl:attribute>
 </xsl:if>

everywhere, instead of just adding an attribute set to param.xsl. Any
reasons?
