4. Obsolete and Proposed Features

4.2 Proposed Features

4.2.1 - Defining Instance
4.2.2 - Special Characters
4.2.3 - Strike
4.2.4 - Underline

This section describes proposed HTML elements and entities that are not currently supported under HTML Levels 0, 1, or 2, but may be supported in the future.

4.2.1 Defining Instance

The Defining Instance element indicates the defining instance of a term. The typical rendering is bold or bold italic. This element is not widely supported.

4.2.2 Special Characters

To indicate special characters, HTML uses entity or numeric representations. Two additional character presentations are proposed:

CHARACTER                  REPRESENTATION
Non-breaking space         &nbsp;
Soft-hyphen                &shy;
Registered	                 &reg;
Copyright                  &copy;

4.2.3 Strike

The Strike element is proposed to indicate strikethrough, a font style in which a horizontal line appears through characters. This element is not widely supported.

4.2.4 Underline

The Underline element is proposed to indicate that the text should be rendered as underlined. This proposed tag is not supported by all HTML user agents.

Example of use:

The text <U>shown here</U> is rendered in the document as underlined.
