org.tm4j.topicmap.utils.XTMWriter .setIDRefPrefix(java.lang.String idRefPrefix)

Sets the string prefix to be applied to a topic ID when specifying the string in a topicRef element. Typically, this should only be set to the default value ('#') for use in XLink based reference syntax (such as XTM). A Hytime-based or other addressing scheme may require different prefixes.
