Linefeed and Carriage Return handling (
for the ALT attribute:
- Internet Explorer: All literal/unencoded or encoded CR/LFs are maintained and displayed as intended.
- Netscape: All unencoded or encoded CR/LFs are collapsed to nothing in ALT display (not the normal method for spacing-character collapsing - usually it would collapse to a single space.)
- Opera: When the SRC attribute is unavailable, ALT contents are displayed;
unencoded CR/LFs are collapsed to a single space, while Encoded entities
are honored and displayed as intended.
