Re: [docbook] Attribute Set for

["Bob Stayton" <bobs@sagehill.net>]

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.
