Examples of net.sf.saxon.expr.XPathContextMajor

net.sf.saxon.expr.XPathContextMajor
This class represents a "major context" in which an XPath expression is evaluated: a "major context" object allows all aspects of the dynamic context to change, whereas a "minor context" only allows changes to the focus and the destination for push output.
