1) Oletetaan, että kontekstisolmu on sitä card-elementtiä vastaava
solmu, jonka ID-attribuutin arvo on "start". /
Assume that the node corresponding to the card-element
with the value "start" of its ID attribute is the context node.

child::name/child::fname
name/fname

parent::dept/oname

ancestor::node()/oname
ancestor::*/oname


2) Oletetaan, että kontekstisolmu on yllämainitun card-elementin
vanhempaa, dept-elementtiä vastaava solmu.

card/email
card[title]/email
card[title="professor"]/email
card/email[@type]
card/email[@type="main"] 

card[position()=1]
card[1]
card[last()]
card[id("start")]
