| * DynAttribsTest test case. |
| * |
| * When a tag is declared in a TLD file as |
| * <dynamic-attributes>true</dynamic-attributes> |
| * then the tag-class must implement the |
| * javax.servlet.jsp.tagext.DynamicAttributes interface. |
| * If a tag's class does not implement this interface, |
| * the the application server will treat the tag as unsafe. |
| * |
| * This test parses the struts-tag.tld file and checks |
| * that each of the tags defined as accepting dynamic |
| * attributes implements DynamicAttributes. |
