public class EscapeNCName
extends SystemFunction

The saxon:escape-NCName function takes an arbitrary string and converts it to an NCName. Characters that are not legal in an NCName are converted to the form _xxxx_. A zero length string is converted to a single underscore. An underscore is converted to a pair of underscores. The conversion can be reversed using saxon:unescape-NCName;
