| /** |
| * This class defines the information about an attribute that will come out |
| * of the scanner during parsing. This information does not depend upon the |
| * type of validator because it is not tied to any scheme/DTD type info. Its |
| * just the raw XML 1.0 information that will be reported about an attribute |
| * in the startElement() callback method of the XMLDocumentHandler class. |
| * Hence it is not intended to be extended or derived from. Its designed to |
| * be used as is. |
| * |
| * The 'specified' field of this class indicates whether the attribute was |
| * actually present or whether it was faulted in because it had a fixed or |
| * default value. |
| * |
| * The code receiving this information can ask its validator for more info |
| * about the attribute, i.e. get its declaration from the DTD/Schema info. |
| * |
| * Because of the heavy use (and reuse) of instances of this class, and the |
| * number of string members it has, this class takes pains to not reallocate |
| * string members unless it has to. It keeps up with how long each buffer |
| * is and only reallocates if the new value won't fit. |
