Not too much:

1. Avoid expressions like "//file_audio" whenever possible. Probably
this is just "file_audio", or "$someFixedPath/file_audio" ?

2.    <xsl:text disable-output-escaping="yes">&#xD;&#xA;</xsl:text>
                ^^^^^^^^^^

This seems strange to me.

The "match" attribute of xsl:key and xsl:template cannot contain
variable references -- this is said in order to prevent circular
definitions, as global variables can be defined using the key()
function or xsl:apply-templates. Due to the same reason the "use"
attribute of xsl:key cannot contain variable references.

Variable references can be used in the value of the "select" attribute
of xsl:apply-templates.

One way to parameterise the usage of keys is to pass their ***name***
as parameter to a template.


Hope this helped.
