If a variable refers to part of an HTML page which is subsequently rewritten, the result may be wrong because the 'old' value of the variable is used. For instance, suppose a template variable is defined as

<xsl:variable name="input" select="ixsl:get(ixsl:page()//div[@id='target']/textarea[@id='input'],'value')"/>

and another template has the action of overwriting the relevant textarea

<xsl:template name="overwrite">
        <xsl:result-document href="#target" method="ixsl:replace-content">
            <textarea data-ref="input"></textarea>
        </xsl:result-document>
    </xsl:template>

Then we do not see the correct new value for $input after the 'overwrite' has been called.

Internally, a key is used for the reference to the textarea node. The issue is that when the textarea is overwritten, the key should be invalidated, so that it is reevaluated properly.
