First point: the character references such as &#10; are converted to regular
characters by the XML parser. The XSLT processor never gets to see the
character references, so it can't pass them through.

Second point: character references such as &#10; are a feature of XML and
HTML, so you can produce them when using the xml and html output methods,
but not when using the text output method. Characters are never escaped with
the text output method, so disabling escaping achieves nothing.

I think you need to use something like (in XPath 2.0) replace('&#10;',
'&amp;#10;')
