public class CreoleXmlUpperCaseFilter
extends XMLFilterImpl

SAX XMLFilter implementation used when reading a creole.xml file to ensure that all the standard creole elements and their attribute names are converted to upper case. All the creole.xml files built into GATE use upper case for their elements and attributes, but historically the files have been treated case-insensitively. Non-standard elements (which are added as features of the resource) are untouched.
