The current INPUT XSL file (which I found & tweaked from

doesn't output the ROOT element,

Because you are matching only on elements that have element parents, which is not true for the document element.


and currently strips all attributes
(it only outputs the parent element if it strips the attribute). With
the exception of the above attributes being output as child elements,
I want to preserve the current XML document.

Then you need to push the child nodes of the elements through the template rules as well ... you are missing <xsl:apply-templates/> in your template rule.


But it isn't that simple. You cannot convert some attributes to elements and then after that add the next attributes that are preserved as attributes.

Below illustrates how one could address your requirement. A quick review of the result looks like it is what you want.

I hope this helps.
