What are the Data Attributes?
This category concerns the common Data Binding attributes found in Internet Explorer 4.0+ - they allow a data source (commonly a field in a database) to be tied to an element.

In HTML 4.x a Parameter Entity called "%reserved" is also defined that contains these same attributes. These attributes are not actually explained or defined in the standard other than a cryptic "reserved for possible future use" notation in the DTD. These attributes do not appear in any XHTML DTDs.

The IE data points in these support charts are taken directly from Microsoft's own documentation on this subject.

Language Attributes
[2|3|3.2|4] [X1|X1.1] [IE4|N|O|S]
Required? No
The column name from the data source object that supplies the bound data.
Values: Alphanumeric characters.
[2|3|3.2|4] [X1|X1.1] [IE4|N|O|S]
Required? No
Indicates whether bound data is plain text or HTML. HTML 4 (plaintext) and Internet Explorer 4 (text) values seem to be different values for achieving the same result.
Values: html | plaintext | text
[2|3|3.2|4|S] [X1|X1.1] [IE4|N|O]
Required? No
Indicates the URL or ID of the data source object supplying the data that is bound to this element. HTML 4 and Internet Explorer 4 diverge here on intent of this attribute - HTML 4 indicates it should be a URL while IE4 says it should be a data source ID.
Values: Data source ID or relative/absolute URL.
