Schematron example

Sets up the name element as the context

<pattern name="Validate name against RNC 
               { given* &amp; family &amp; title? }">
  <rule context="name">
    <assert test="family">'family' element is missing</assert>
    <report test="*[not(self::given | self:: family | 
                    self::title)]">Element not allowed</report>
    <report test="text()[normalize-space()]">Text content not 
       allowed</report>
    <report test="count(family) > 1">More than one 'family' 
       element is not allowed</report>
    <report test="count(title) > 1">More than one 'title' 
       element is not allowed</report>
  </rule>
</pattern>
