All Known Implementing Classes:

TextArea, TextField
```
public interface RegexElement
```
Interface to add regex pattern to elements, thus the following attributes: pattern (the regex, it will be tested if it compiles), not mandatory pattern-error-message, mandatory when pattern is added (in PresentationML it is translated to data-pattern-error-message) Simply implement it into the element when you want to add regex support Beware: If the element implementing this interface overrides Element.validate() and/or Element.buildAttribute(org.symphonyoss.symphony.messageml.MessageMLParser, Node) and/or Element.asPresentationML(XmlPrintStream, org.symphonyoss.symphony.messageml.MessageMLContext) without calling super, it is needed to manage manually PATTERN_ATTR and PATTERN_ERROR_MESSAGE_ATTR in these methods
