XSLT: Date Format to Long Date

I am working on some XSL for a PDF that I believe uses an engine, FOP. At the moment I am trying to display a date format from MM/dd/yyyy to a long date (Jan 1 , 1990)

The XML is like this:

<?xml version="1.0" encoding="UTF-8"?>
<hash>
 <cf_customer_quotation_expiration_date type="date">2014-11-08</cf_customer_quotation_expiration_date>
</hash>

The XSL contains the following code by default:

<fo:block text-align="right">
    <xsl:call-template name="date:format-iso8601-date">
        <xsl:with-param name="iso8601-date">
            <xsl:value-of select="/hash/document_date_iso8601" />
        </xsl:with-param>
    </xsl:call-template>
</fo:block>

And in case anyone is interested in the stylesheet formatters:

<?xml version="1.0" encoding="UTF-8"?>
<xslt:stylesheet xmlns:xslt="http://ift.tt/tCZ8VR" xmlns:date="http://ift.tt/HkOdXa" xmlns:fo="http://ift.tt/vyPH5E" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:str="http://ift.tt/rkTpc5" xmlns:svg="http://ift.tt/nvqhV5" xmlns:xc="http://ift.tt/13Ro5zj" xmlns:xf="http://ift.tt/10uz9Lr" xmlns:xfd="http://ift.tt/13Ro7aw" xmlns:xsl="http://ift.tt/tCZ8VR" version="1.0" extension-element-prefixes="date str">
    <xslt:output indent="yes" encoding="utf-8" />
    <xsl:template match="/">



    <xslt:template name="date:format-iso8601-date">
        <xslt:param name="iso8601-date" />
        <xslt:variable name="format">
            <xsl:choose>
                <xsl:when test="/hash/text/Date_Format != &quot;&quot;">
                    <xsl:value-of select="/hash/text/Date_Format" />
                </xsl:when>
                <xsl:otherwise>"dd/MM/yyyy"</xsl:otherwise>
            </xsl:choose>
        </xslt:variable>
        <xsl:choose>
            <xsl:when test="$format = &quot;yyyy-MM-dd&quot;">
                <xsl:value-of select="$iso8601-date" />
            </xsl:when>
            <xsl:when test="$format = &quot;MM/dd/yyyy&quot;">
                <xsl:value-of select="substring($iso8601-date, 6, 2)" />
                /
                <xsl:value-of select="substring($iso8601-date, 9, 2)" />
                /
                <xsl:value-of select="substring($iso8601-date, 1, 4)" />
            </xsl:when>
            <!-- Default to dd/MM/yyyy -->
            <xsl:otherwise>
                <xsl:value-of select="substring($iso8601-date, 9, 2)" />
                /
                <xsl:value-of select="substring($iso8601-date, 6, 2)" />
                /
                <xsl:value-of select="substring($iso8601-date, 1, 4)" />
            </xsl:otherwise>
        </xsl:choose>
    </xslt:template>
</xslt:stylesheet>
