[xsl] Matching a list of attributes

[chris <oneskiingfool@xxxxxxxxx>]

Hello,
Probably an easy question...  I'll use sql-like notation to
demonstrate what I want to do...

<xsl:template match="volume/book[chapter/@title in ('monkeys','buffalo')]"/>

So in this example I would want to match any book that had a chapter
titled 'monkeys' or 'buffalo'.

I realize I can do this, but this will get very tedious...
<xsl:template match="volume/book[chapter/@title = 'monkeys'] |
volume/book[chapter/@title = 'buffalo']"/>

I'm using xpath & xslt 2.0.

Any ideas?  Thanks!
