A field for data entry in a dialog window.
If the optional select attribute is used, its value is displayed in the field when the runtime user enters the dialog. It is a default value: the user can choose to overwrite it. Expr is either a string literal or an XPath expression.
If you set multiline="yes", the field is allowed to be multi-line, that is: it is able to have variable height. Use the h attribute to set the height you want:
The optional passwordchar attribute may be used to mask password input. It masks each character typed by the runtime user by displaying passwordchar instead of the input character. passwordchar is a single non‑whitespace character, typically an asterisk ( * ).
This example asks the user to provide a password.
