You need to establish a namespace binding in the XPath context for the
default namespace in the source document. For example, if you establish that
the prefix 'f' is mapped to the default namespace (e.g., 'uri-foo'), you
would write the location path as follows /f:foo/f:bar/f:baz.

How you establish the namespace bindings depends on the implementation that
you're working with. For example, MSXML (sept. release) provides the
setProperty method for doing this as follows:

doc.setProperty "SelectionNamespaces", "xmlns:f='uri-foo'"

If you're working in an XSLT document, you do this by simply supplying the
appropriate namespace declarations in the document itself:

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:f="uri-foo" version="1.0">
   <xsl:template match="f:foo">
   ...
</xsl:transform>

All XPath implementations *should* provide a way to establish the context of
namespace bindings.
