    <?xml version="1.0" encoding="UTF-8"?>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
        <xsl:import href="x.xsl"/>
        <xsl:template match="/">
            <html>
                <head>
                    <title>Test</title>
                </head>
                <body>
                    <h1>Current page is</h1>
                    <xsl:call-template name="Content"/>
                </body>       
        </html>
        </xsl:template>
    </xsl:stylesheet>

- PageA.xsl

    <?xml version="1.0" encoding="UTF-8"?>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

        <xsl:import href="PageFrm.xsl"/>
       
        <!-- Invoked by PageFrm.xsl -->
        <xsl:template match="Content">
            PageA
        </xsl:template>

    </xsl:stylesheet>

- PageB.xsl

    <?xml version="1.0" encoding="UTF-8"?>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

        <xsl:import href="PageFrm.xsl"/>
       
        <!-- Invoked by PageFrm.xsl -->
        <xsl:template match="Content">
            PageB
        </xsl:template>

    </xsl:stylesheet>

Run PageA.xsl and PageB.xsl, you will see the different result.
