Not sure if by "fail" you mean the <xsl:when test tests as false or you

a value of that type in the xpath type system or something that looks
like an intger, eg "123".
I'm not sure either :-)
Here's an example template:
<xsl:template match="mods:extent[(_at_)unit='page']">
<xsl:param name="prefix"/>
<xsl:param name="suffix"/>
<xsl:value-of select="$prefix"/>
<span class="pages">
<xsl:text> pp. </xsl:text>
<xsl:value-of select="mods:start"/>
<xsl:if test="mods:end">
<xsl:text>–</xsl:text>
<xsl:value-of
select="bib:number-condense(mods:start,mods:end)"/>
</xsl:if>
</span>
<xsl:value-of select="$suffix"/>
</xsl:template>
.... and the original function:
<xsl:function name="bib:number-condense">
<xsl:param name="begin"/>
<xsl:param name="end"/>
<xsl:choose>
<xsl:when test="$begin castable as xs:integer">
<xsl:variable name="begin" select="$begin" as="xs:integer"/>
<xsl:choose>
<xsl:when test="$begin gt 100 and $begin mod 100 and $begin
idiv 100 eq $end idiv 100">
<xsl:value-of select="$end mod 100"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$end"/>
</xsl:otherwise>
</xsl:choose>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$end"/>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
It has not failed yet (as in, Saxon never stops in its tracks with a
type error, and it formats the page ranges as I expect them to be
formatted), but it's not been widely tested.
