The following code snippet compiles without error:

	private static Exp COMPLEXEXTENSION_CHILDREN =
	sFac.concat(
		sFac.optional("annotation"),
		sFac.concat(
			sFac.optional(
				sFac.union(new String[] 
{"group","all","choice","sequence"})),
			sFac.concat(
				sFac.star(
					sFac.union(new String[] 
{"attribute","attributeGroup"})),
				sFac.optional("anyAttribute"))));
	//Content: (annotation?, ((attribute | attributeGroup)*, 
anyAttribute?))
	private static Exp SIMPLEEXTENSION_CHILDREN =
	sFac.concat(
		sFac.optional("annotation"),
		sFac.concat(
			sFac.optional(
				sFac.union(new String[] 
{"group","all","choice","sequence"})),
			sFac.concat(
				sFac.star(
					sFac.union(new String[] 
{"attribute","attributeGroup"})),
				sFac.optional("anyAttribute"))));

When the following line is added:

	private static Exp GROUP_CHILDREN =

(an incomplete declaration) the compiler erroneously marks each first instance 
of a comma in the String initializers preceding it as an error, with the error 
message:

Syntax error: ",",...expected

The character marked _is_ a ","!

To be perfectly clear, an error after these declarations is incorrectly 
causing bogus errors to be flagged within the declarations, before the actual 
error. The resulting blizzard of error flags makes it very difficult to work.

BTW, change the above line to, e.g.:

	private static Exp GROUP_CHILDREN = Exp.Epsilon;

And all the bogus errors preceding it go away.
