XSLT for toplevel element in xml

Hi:

I have a xml say One.xml that has the toplevel element as the following --

<abc:configuration xmlns:abc="http://oracle.com/xmlns/abc/configuration"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" locale="en"
cache="false" rmi="true">
...
..
....
....
</abc:configuration>


I need to transform One.xml to Two.xml in such a way that Two.xml contains some additional attributes in the abc:configuration tag
ie

<abc:configuration xmlns:abc="http://oracle.com/xmlns/abc/configuration"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" locale="en"
cache="false" rmi="true" new_tag="true" new_tag2="false">

I tried to use several ways as rules for the <xsl:template match=.....--
1) template match="abc:configuration"
2) template match="local-name(abc:configuration)
3) template match="@*[(starts-with(name(),'abc:'))]"

But it does not work. Only after replacing the abc:configuration by configuration in One.xml and writing a rule to match configuration it works.
Can you suggest a resolution to this?

Thanks, Nishi.
