Syntax
key of data-attribute of (attribute-reference)
An operation that returns the "true" name of the attribute. This is most useful when retrieving the real name of an attribute that is being referenced through an alias. The name is uppercased when the SGML declaration specifies NAMECASE GENERAL YES for the SGML document being processed.
Because attributes are always considered part of a shelf of attributes, it always makes sense to ask for the "key" of an attribute, even if the data-attribute form is used rather than data-attributes.
