newbie question - possible to select page-master based on xml attribute?

I have a problem with selecting page layout types - outlined below, and
would appreciate any advice anyone could give me on this. Even to
confirm whether my assumptions are correct or not, would be really
helpful.

I'm working on a project where an XSL document is used to transform XML
into xsl:fo, then into PDF - not using any extensions or docbook or
anything. I'm making some sample xml and xsl files and using a wee app
called Felix to do the xml + xsl > xsl:fo, and then a desktop version of
APOC to generate the PDF from xsl:fo.

What I have got is one document with  a series of <chapter> elements -
the first few are some specialised pages (cover page, table of
contents), then there's  a series of <chapter> elements which are in
section cover / section content pairs. 

Sample XML for this:

<document>
	<chapter pageType="coverPage"> // only one of these in the
document
	... Cover page text for the document...
	</chapter>

	<chapter pageType="tocPage"> // only one of these in the
document
	... Table of contents...
	</chapter>


	// then a series of chapter coverpage / content pairs:

	<chapter pageType="sectionCoverPage"> 
	... This is a section cover page...
	</chapter>

	<chapter pageType="sectionContent">
	... And the section content...
	</chapter>

</document>

What I want to be able to do, is have a page-master selected and used
for each <chapter>, based on it's value for pageType - for example,
defining the set of page layouts in the XSL something like:

<fo:layout-master-set>
	<fo:simple-page-master master-name="docCover">
	... Definitions...
	</fo:simple-page-master>
             
	<fo:simple-page-master master-name="docToc">
	... Definitions...
	</fo:simple-page-master>

	<fo:simple-page-master master-name="chapterCover">
	... Definitions...
	</fo:simple-page-master>

	<fo:simple-page-master master-name="chapterPage">
	... Definitions...
	</fo:simple-page-master>                          
</fo:layout-master-set>

From what I've read it isn't possible to assign a simple-page-master
based on content that's in the flow (ie in this case an attribute value)
- it looks as if you can specify which page-master to used based on a
small set of conditions (first page, odd or even, etc), none of which
quite fit here. 

So I am thinking that I'll have to rethink this approach and change the
XML structure - unless there is a way to do what I've outlined above.
(I'm trying to avoid having to change the XML structure as this needs to
be integrated into an existing system - creating new XML elements in my
document would require these to then be integrated into the existing
system...)

Any advice on this would be much appreciated,

Cheers,
Rebecca Cox
