/// This call escapes '&', '<, '>', '\'', '"' per the xml spec and removes all

//
/// This call removes all invalid characters as defined by Section 2.2 of the
/// xml spec. If you are writing XML yourself, you probably was to use the
/// above api (gtm_stringBySanitizingAndEscapingForXML) so any entities also

// Returns:
// Autoreleased NSString

- (NSString *)gtm_stringBySanitizingToXMLSpec;
// There is no stringByUnescapingFromXML because the XML parser will do this.
// The above api is here just incase you need to create XML yourself.
