It looks like MarkLogic 4.2 now prepends the
XML version/encoding header for you when serializing
a document. On 4.1 and older, that is not the case
it just serializes the nodes in the document.
Note that an XML "processing instruction" is
not part of the XML document (it's not even an
actual PI), it's meta-information about how to
process the serialized XML document that follows.
Here are two examples of how to generate
serialized XML output with an XML header.
4.2:
xquery version "1.0-ml";
declare function local:my-node() as element(foo)
{
<foo bar="baz">
<blah>flerp</blah>
</foo>
};
let $foo := local:my-node()
return
document { $foo }
4.1:
xquery version "1.0-ml";
declare function local:my-node() as element(foo)
{
<foo bar="bax">
<blah>flerp</blah>
</foo>
};
let $xml-pi := '<?xml version="1.0" encoding="UTF-8"?>'
let $foo := local:my-node()
return
fn:concat ($xml-pi, "
", xdmp:quote ($foo))
