/**
 * This is a seriously sick fix for the fact that some .xlsx
 *  files contain raw bits of HTML, without being escaped
 *  or properly turned into XML.
 * The result is that they contain things like >br<,
 *  which breaks the XML parsing.
 * This very sick InputStream wrapper attempts to spot
 *  these go past, and fix them.
 * Only works for UTF-8 and US-ASCII based streams!
 * It should only be used where experience shows the problem
 *  can occur...
 *  
 *  @deprecated 3.16-beta2 - use ReplacingInputStream(source, ">br<", ">br/<")
