| Provides for parser recognition and parser dependent code. |

| <p> |
| Digester aims to support the widest range possible of parsers. |
| Unfortunately, there are a few parser settings which have no been standardized. |
| In most cases, the best practice is for the user to configure the parser |
| themselves and pass it to Digester to use. |
| </p> |
| <p> |
| There are a few reasonable exceptions which Digesters makes to this general rule. |
| There are a small number of common use cases where insisting that the user |
| configure the parser may reduce the portability of applications using Digester. |
| These are outlined below. |
| </p> |
| <h4>Validating With Schema</h4> |
| <p> |
| When validating using schemas (rather than DTDs), |
| settings for schema language and schema location are commonly needed. |
| Unfortunately, there is a lack of standardization for these settings. |
| In particular, for older versions of Xerces, these are set differently |
| from newer versions. |
| </p> |
| <p> |
| In order to aid portability for this common use case, Digester uses |
| the classes in this package (together with <code>ParserFeatureSetterFactory</code>) |
| to guess the parser and set these properties appropriately. |
| The aim is for Digester to automagically recognize and configure each parser. |
| Help would be gratefully appreciated to maintain and improve the support in this area. |
