Extra nesting using DBMS_XMLGEN.getxml and Cursor expression <xmltag_ROW>

I've been searching the documentation and google but I can't seem to
find what I am looking for.

Let's use this simple query:

select dbms_xmlgen.getxml('select cursor(select ''1'' "one", ''2''
"two", ''3'' "three" from dual) "numbers" from dual')
from dual;

the result is:

"<?xml version="1.0"?>
<ROWSET>
 <ROW>
  <numbers>
   <numbers_ROW>
    <one>1</one>
    <two>2</two>
    <three>3</three>
   </numbers_ROW>
  </numbers>
 </ROW>
</ROWSET>
"

Question1: Why was <numbers_row> created when <numbers> is sufficient
(at least for my purposes)?

Question2: Can I get rid of that extra nesting with the xmlgen package
or some other package? I'm using regular expressions to do so but it
seems a bit unreasonable.

Thank you,
