      sk.uniba.euromath.document.schema.impl.loader.GrammarRulesModifier

public final class GrammarRulesModifier
extends ExpressionCloner

Modifies given grammar, so it has following features:

• Every expression is simplified via the Expression.getExpandedExp() method.
• Every OtherExp and ReferenceExp is replaced by its child expressions. They are simply removed from grammar.
• When allowOtherNs, then each element's child expression is replaced by following expression: (<@EP>+|e).((EP+|e) INTERLEAVE original_child), where ALL is nameclass accepting everything but local namespace.
• Every nameclass is modified so it doesn't accept anything from Const.EM_URI_SELECT namespace.
