Hi everyone,

    In experimenting with XmlDataDocuments, I've come across a bit of a
head-scratcher-- likely because of my incomplete understanding of the
class.

    I've run through the steps listed below successfully, excluding the last
step, which throws an exception.

    That is, I've:

    --Built a simple DataSet by hand with a three-column table and added a
few test records.
    --Passed this DataSet into an XmlDataDocument constructor.
    --Immediately saved the XmlDataDocument to a StringWriter.
    --*Tried* to read the XML into a new DataSet, using the ReadXml method.

    This is where I get hit with an exception, which says, "There are
multiple
root elements."  The error originates in the ParseRoot() method of the
XmlTextReader class.

    I never touched the XML generated by the XmlDataDocument's Save()
method, so
I'm not entirely sure what's wrong.  It --appears-- the XmlDataDocument's
Save
method doesn't provide XML that a DataSet can read from.  This is a little
counterintuitive to me; I mean, wouldn't it stand to reason that a DataSet
can load an XmlDataDocument's output?

    I may be reading too much into this --I can always just copy the
XmlDataDocument's DataSet member to my DataSet, after all-- but I wondered
if I was
doing something wrong when saving the XML or loading it into the new
DataSet.

    Thanks for the clarifications.
