The "ToString()" is not implemented, and thus returns "MgByteReader",
which you cannot use as an XML document.<br>
<br>
The MgByteReader is very volatile and fragile, when you try to debug it
with VS.<br>
Any attempt to pass the byte reader to a function (as a parameter) will
clear the stream.<br>
You cannot read more than 8kb out of the stream in a single Read()
operation, making it a royal pain to use the MgByteReader.<br>
<br>
I have seen others using an MgByteSink, but I have yet to try that.<br>
