It is with your code, and obviously Saxon 6.3 implements XSLT 1.1,
otherwise you'd have an error reported on your attempt to use the RTF
(Result Tree Fragment) as a node-set.

The problem is that an RTF, when converted to a node-set is a separate
xml document, so the following code:

>         <xsl:apply-templates select="$add-apply-button">
>             <xsl:with-param
> name="submit-form">AddEditView</xsl:with-param>
>         </xsl:apply-templates>

will apply a template to the root (/) of the document, to which
$add-apply-button evaluates.

Probably your template (if any) matching / does not care for any
parameters, nor it passes them down to any templates applied on /node()

The solution is to replace the above with:

         <xsl:apply-templates select="$add-apply-button/*">

in case you're using an XSLT 1.0 complient XSLT processor, you'll have
to use vendor:node-set($add-apply-button)/*
