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.

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