Matra - an XML DTD Parser

I am adapting the Matra code for my own uses and I came
across this bug. In the AttList.toString method (line
323) it has attlist += enums[enums.length - 1] + ") ";


When the enums array is empty this line causes a
java.lang.ArrayIndexOutOfBoundsException to be thrown.
I switched this line in my version of the code to:

if (enums.length > 0) {
attlist += enums[enums.length - 1] + ") ";
} else {
attlist += ") ";
}
