| public static java.lang.String | convertName(java.lang.String name)Convert a DTD name into a bean name:
Any - or _ character is removed. The letter following - and _
is changed to be upper-case.
If the user mixes upper-case and lower-case, the case is not
changed.
If the Word is entirely in upper-case, the word is changed to
lower-case (except the characters following - and _)
The first letter is always upper-case.
CharacterIterator ci;
StringBuffer n = new StringBuffer();
boolean up = true;
boolean keepCase = false;
char c;
// hack need for schema2beans limitation.
if(name.equals("property")) {
name = "element-property";
}
ci = new StringCharacterIterator(name);
c = ci.first();
// If everything is uppercase, we'll lowercase the name.
