sequence unparsed-text(sequence uris, String encoding?)
For example, to include a text document as an example:
<example href="examples/bib.xml"/>
<xsl:template match="example">
<pre><code><xsl:value-of select="unparsed-text(@source)"/></code></pre>
</xsl:template>
Can also be used to load non-XML data such as tab-delimited text for parsing; e.g. with regular expressions
