Agreed.  The solution we use is something like:

<?xml version="1.0"?>
<page>
        <title><?php 1 < 1 ? 7 & 8 : "'"; ?></title>
</page>

<?xml version="1.0"?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="1.0">
        <xsl:output method="html"/>
        <xsl:template match="node() | @*">
                <xsl:copy select=".">
                        <xsl:apply-templates select="node() | @*"/>
                </xsl:copy>
        </xsl:template>
        <xsl:template match="processing-instruction()">
                <xsl:processing-instruction name="php">
                        <xsl:value-of disable-output-escaping="yes" 
select="."/>
                        <xsl:text>?</xsl:text>
                </xsl:processing-instruction>
        </xsl:template>
</xsl:transform>

Obviously, this doesn't allow php in mid-elements, but this is easy enough 
to work around by just outputting the entire opening/closing tags in PHP.
