60 /**
61  * A generic grammar for use in validating XML documents. The Grammar
62  * object stores the validation information in a compiled form. Specific
63  * subclasses extend this class and "populate" the grammar by compiling
64  * the specific syntax (DTD, Schema, etc) into the data structures used
65  * by this object.
66  * <p>
67  * <strong>Note:</strong> The Grammar object is not useful as a generic
68  * grammar access or query object. In other words, you cannot round-trip
69  * specific grammar syntaxes with the compiled grammar information in
70  * the Grammar object. You <em>can</em> create equivalent validation
71  * rules in your choice of grammar syntax but there is no guarantee that
72  * the input and output will be the same.
73  *
74  * <p> Right now, this class is largely a shell; eventually,
75  * it will be enriched by having more expressive methods added. </p>
76  * will be moved from dtd.Grammar here.
