[xsl] Uncontrolled navigation around a document using @* ... huh?

["Costello, Roger L." <costello@xxxxxxxxx>]

Hi Folks,

The XSLT 3.0 specification introduces a new function for obtaining the
attributes on a node, fn:attributes.

fn:attributes has some desirable properties that @* does not have:

	Unlike the attribute axis, @*, the
	fn:attributes function returns atomized
	attribute values, which cannot be
	used as the base for uncontrolled
	navigation around the document.

Huh?

What does that mean? How does @* enable "uncontrolled navigation around the
document." What does that mean? Would you provide an example to illustrate
this "uncontrolled navigation" please?
