No. Your two examples are the same. They are just data encoded in XML. As
being discussed at present in another thread, the xsl:value-of might just
be input data to a process that produces canonical  xslt, or Xquery or
whatever.  Conversely the airport xml could be processed by some auto-pilot
system to control a flight . In what way are the two fragments different?
