 22    * Constructs {@link org.apache.tapestry.form.validator.Validator} instances from a specification. A
 23    * specification is a comma-seperated list of entries. Each entry is in one of the following forms:
 24    * <ul>
 25    * <li><em>name</em>
 26    * <li><em>name</em>=<em>value</em>
 27    * <li><em>name[<em>message</em>]</em>
 28    * <li><em>name</em>=<em>value</em>[<em>message</em>]
 29    * <li>$<em>name</em>
 30    * </ul>
 31    * <p>
 32    * Most validator classes are <em>configurable</em>: they have a property that matches their
 33    * name. For example, {@link org.apache.tapestry.form.validator.MinDate} (which is named "minDate"
 34    * has a <code>minDate</code> property. A few validators are not configurable ("required" =>
 35    * {@link org.apache.tapestry.form.validator.Required}, for example).
 36    * <p>
 37    * Validators are expected to have a public no-args constructor. They are also expected to have a
 38    * <code>message</code> property which is set from the value in brackets.
 39    * The message is either a literal string, or may be prefixed with a '%' character, to indicate
 40    * a localized key, resolved using the component's message catalog.
 41    * <p>
 42    * When the name is prefixed with a dollary sign, it indicates a reference to a <em>bean</em>
 43    * with the given name.
 44    * <p>
 45    * A full validator specification might be:
 46    * <code>required,email[%email-format],minLength=20[Email addresses must be at least 20 characters long.]
