SQL Select Statement for XML Explicit formatting from a single table

I have a simple table that has data I need to export to an XML formatted file.  I can get the data formatted correctly when it is one record but when there is 2 or more the Select..for XML explicit statement seems to be incorrect.  I have tried many iterations with no success.  Here is the temporary table format followed by the Select statement and what I'm trying to get out of the statement.

TagName      TimeStamp            Value
ABCDEFG      2008-04-02 04:11:00      12345
WXYZ      2008-04-02 16:15:00      98765

This is the format that I need
<Import>
<DataList Version="1.0.71">
<Tag Name="ABCDEFG"/>
  <Data>
    <TimeStamp>2008-04-02 04:11:00</TimeStamp>
    <Value>12345</Value>
    <DataQuality>GOOD</DataQuality>
  </Data>
</Tag>
<Tag Name="WXYZ">
  <Data>
    <TimeStamp>2008-04-02 16:15:00</TimeStamp>
    <Value>98765</Value>
    <DataQuality>GOOD</DataQuality>
  </Data>
</Tag>
</DataList>
</Import>

This is the current SQL statement I'm using.

I can't seem to get the TagName to nest within the output.  I seem to show all the TagNames at the beginning of the statement and not within the XML format structure.

Any help would be greatly appreciated.
