Hello Michael, It's a long standing bug [1] and has been broken for so long I'm not sure any version of Xerces 2.x ever supported the feature. It's been on my TODO list for awhile and I'm hoping to finally get around to it for Xerces 2.8.0.
By the way you weren't actually using Xerces 2.7.1 when you ran your test (probably since you didn't put the Xerces jars on the classpath). The com.sun.org.apache.xerces.internal.* packages originate from Sun's Java 5.0. Thanks.
