How can escape characters in source tree be preserved in result tree?

I am writing an XSL which is meant to transform one XML file into another XML file. The source tree contains & in a text node. I want that preserved in the result tree, but after output, it becomes a naked &.

I have my <xsl:output> with the following attributes: method="xml", version="1.0", encoding="UTF-8", standalone="yes".

I've tried using a character map for & (can't do this because naked & is invalid XML, and XSL is XML), for &amp; (doesn't match anything), and &amp;amp; (is more than one character, so can't fit into @character of <xsl:output-character>

If I change the source XML instances of &amp; to &amp;amp;, then the XSL output has the desired &amp;. I don't want to introduce another step into the process, however.

I've also tried making the output html. This didn't help.

I tried to use cdata-section-elements for the result nodes that might contain &amp;, but I get an error from parser: Value of {cdata-section-elements} must be a list of QNames in '{uri}local' notation

You have explicitly asked the processor not to escape the ampersand, by using disable-output-escaping="yes". If you want it escaped, then don't disable escaping.
