◆ retrieveProperty()

QString SystemPropertyFN::retrieveProperty ( const QXmlName  name)
staticprivate

Returns a string representation for property as defined for the system properties in "XSL Transformations (XSLT) Version 2.0, 16.6.5 system-property". Hence, this function handles only the properties specified in the XSL namespace, and returns an empty string if an unrecognized property is asked for.
