Book title in page footer

Hello,

I have a book title like this "AA<superscript>2</superscript>BB".

I have my own footer where this book
title should appear at center. I have the following xsl-code:

<xsl:when test="($sequence =
'odd' or $sequence = 'even') and $position = 'center'">

        <xsl:value-of
select="ancestor-or-self::book/title">

</xsl:when>

Works also fine but the superscript
is removed. I think the reason is the "ancestor-or-self".

Please give me a hint how can I insert
the book title in the footer with the footer.

Thanks in advance

Steffen

Mit freundlichen Grüßen / Kind regards

Steffen Köhler
