Hello,
it seems to me there is a couple of issues concerning the handling of indentation (serialization parameter "indent").
a) Using "indent=no" whitespace-only text nodes between element nodes are removed b) Using "indent=yes" the content of elements with xml:space="preserve" is indented, too I suppose both behaviors are in contraction to the spec ( http://www.w3.org/TR/xslt-xquery-serialization/#xml-indent ).
As a particular consequence, (a) seems to preclude making an exact copy of a document (fragment) - all whitespace-only text nodes vanish.
And as a consequence of (b) one has no possibility to locally protect the whitespace used in the source document, as required for example when reusing "programlisting" elements of docbook.
Or did I overlook something?
Kind regards, Hans-Juergen
