namespace woes

Hi -

I have a xsl stylesheet that uses str:split to convert a value into
fragment.

e.g.
...
<id>10.20.50</10>
...

Becomes

<root xmlns="http://www.w3.org/1999/XSL/Transform">
  <pg id=10.20.50>
    <s>10</s>
    <s>20</s>
    <s>50</s>
  </pg>
</root>

Everything works great except, my root node is output with the default
namespace. This causes me much grief when I try to access a node by name
with an XPath expression.

My question is. How do I reference a node in the namespace context as
noted above, or how can I prevent str:split from outputting the default
namespace?

Thanks in advance,
