/**
 * Turn a COBOL name to an XSD element name.
 * <p/>//from   w w w  .j a  va 2s. c  om
 * COBOL names look ugly in XML schema. They are often uppercased and use
 * hyphens extensively. XML schema names they will have to be transformed
 * later to java identifiers so we try to get as close as possible to a
 * naming convention that suits XML Schema as well as Java.
 * <p>
 * So we remove hyphens. We lower case all characters which are not word
 * breakers. Word breakers are hyphens and numerics. This creates Camel
 * style names. Element names customarily start with a lowercase character.
 * <p/>
 * COBOL FILLERs are a particular case because there might be more than one
 * in the same parent group. So what we do is systematically append the
 * COBOL source line number so that these become unique names.
 * <p/>
 * COBOL names can start with a digit which is illegal for XML element
 * names. In this case we prepend a "C" character.
 * <p/>
 * Since Enterprise COBOL V4R1, underscores can be used (apart from first
 * character). We treat them as hyphens here, they are not propagated to the
 * XSD name but are used as word breakers.
 * <p/>
 * Once an element name is identified, we make sure it is unique among
 * siblings within the same parent.
