Note

The result of the substitution may be either an absolute or a relative URI reference. In the latter case it is combined with the value of xml:base in force at the place where the cRef attribute occurs to form an absolute URI in the usual manner as prescribed by XML Base.

Example
<cRefPattern matchPattern="([1-9A-Za-z]+)\s+([0-9]+):([0-9]+)"
 replacementPattern="#xpath(//div[@type='book'][@n='$1']/div[@type='chap'][@n='$2']/div[@type='verse'][@n='$3'])"/>
Content model
<content>
 <classRef key="model.pLikeminOccurs="0"
