the id is unique within a run of the stylesheet so it can be used in
xslt code to identify a node as in <xsl:if
test="generate-id(.)=generate-id($xx)">
or it can be used to generate ids and internal links in teh output so
long as you don't mind that they are unstable and change if document
regenerated.

To get stable ids either get them from the source or use something like
<xsl:number/> to generate a unique id.
ie <xsl:attribute name="id">foo<xsl:number level="any"
count="foo"/></xslattribute"/>

will generate attribute values  foo1 foo2 etc on foo elements.
