are present in the form but empty (or optionally given default data). These types of forms are
uncomplicated and easy to design.
Flowing layout strategy, version 2.1
In flowing layout, containers may be positioned from top-right to bottom-left. Additionally, flowing layout
also supports tables, as described in
“Flowing layout support for tables and table-rows, version 2.1”
(below).
Previously, text layout could flow only from left to right.
Flowing layout support for tables and table-rows, version 2.1
Flowing layout now supports tables, by allowing subforms to specify a layout strategy for tables. If such a
subform contains child subforms that specify a layout strategy for rows, the implied columns and rows are
kept in sync with one another.
Rich Text
Embedded objects, version 2.1
Rich text may now include references to text or images. Such references may be expressed using the
Scripting Object Model (for internal references) or using URI’s (for external references). Embedded objects
are resolved dynamically.
Subscript and superscript support, version 2.1
Rich text may now employ the superscript and subscript markup defined by[XHTML].
Accessibility and User Interface
New Widget Types
Signature widget, version 2.1
There is a new type of widget defined for use in affixing a digital signature to a form.
Image entry widget, version 2.1
There is a new type of widget defined for use in picking an image for entry into a form.
Rich text option for text widget, version 2.1
The text widget can now optionally accept rich text from the user and allow editing of existing rich text.
Widget Appearance
Widget margins, version 2.1
Any of the user interface widgets may specify a margin, which insets from the edge of the containing field.
The margin prevents the widget from being eclipsed by the field’s border, especially in the situation where
the border is wide and is even- or right-handed.
