How to copy attribute value to text?

If I start with an input XML document that contains mixed text with <word>
elements like this:

	b& this is just <word correction=btoob>to</word> funny

Ibd like to write an XSLT stylesheet that yields as output

	b& this is just <word origerror=btob>too</word> funny

So in the output I effectively want (in the same <word> element) to

	1.  Set the value of a new attribute to the original text() value, and
	2.  Reset the text() value to be the value of the original @correction
attribute

Ibve tried many variants of the following, so far without success.  Ibm
using SaxonHE9-7-0-6J;
it runs, but the results are not as expected/hoped.

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

        <xsl:output method="xml" indent="yes"/>

        <xsl:template match="node()|@*">
                <xsl:copy>
                        <xsl:apply-templates select="node()|@*"/>
                </xsl:copy>
        </xsl:template>


				<xsl:template match="word[@correction]">

					<xsl:variable name="origtext" select="."/>
					<xsl:variable name="correction">
						<xsl:value-of select="@correction"/>
					</xsl:variable>

					<xsl:copy>
						<xsl:copy-of select="@*[name()!='correction']"/>
						<xsl:attribute name="origerror" select="$origtext"/>
						<xsl:value-of select="$correction"/>
					</xsl:copy>

				</xsl:template>
</xsl:stylesheet>

Ibve tried matching the text() in a separate template, but I canbt seem to
reference the attribute values of the parent node (i.e., <word>) of the text()
and the parent nodebs attributes.  E.g, the following doesnbt work for me,
failing somehow in the
select=b../@correctionb  reference.

<xsl:template match=bword[@correction]/text()b>
	<xsl:value-of select=b../@correctionb/>
</xsl:template>

Any help would be much appreciated.
