This is an SGML Document Access (SDA) attribute. SDA attributes are designed to transform HTML (and other SGML-based documents) to the ICADD DTD - which is used in creating accessible documents for users with visual disabilities (rendering in Braille, large print, speech synthesis, etc.) The attribute value specifies content to be added BEFORE the original element content (in this case the string "<LHead>Select #AttVal(Multiple)</LHead>") when the SDA document is rendered (SDA also allows attributes and values from the original element to be used in the new SDA element where necessary.) "#AttVal(Multiple)" references the value of the SELECT MULTIPLE attribute, if present.

Standards Details: In all HTML 4.x/XHTML DTDs
Required? No
Description:
"Tabbing" is a method of giving access/focus to an active HTML element using a standard keyboard sequence. All the active elements in a document can be cycled through using this sequence (ex: Windows TAB key.) The order of the active elements in this cycle is usually the order they occur in the document, but the TABINDEX attribute allows a different order to be established. The use of this attribute should create the following tabbing order cycle if the browser supports the attribute:
  1. Active elements using the TABINDEX attribute with positive integers are navigated first. Low values are navigated first.
  2. Active elements not specifying any TABINDEX attribute
Those elements carrying a DISABLED attribute or using negative TABINDEX values do not participate in the tabbing cycle.
Values: Positive or negative integers.
