Subject: Drop toplevel XML-comments in libxml-parse-(xml|html)-region?

Hi,
parse_region from xml.c, which is called by `libxml-parse-xml-region'
and `libxml-parse-html-region', makes some effort to retain top-level
comments in xml documents. If necessary it adds an artificial node at
the top of the parse tree. As a consequence one has to check whether
the result contains the "top" node or not (see below for an example).
This behaviour is different from that of `xml-parse-region' (from
xml.el), which just discards the toplevel comments.
Can we make `libxml-parse-(xml|html)-region' consistent with
`xml-parse-region', i.e. can we drop the toplevel xml comments (and
simply call xmlDocGetRootElement)?
Ulf

while for

one gets
(foo nil "bar")
without the artificial node "top".
