| Summary |
String
The name of the attribute. |
key of specified? data-attributes (of ( attribute-reference))? @ numeric-expression
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 namecase general yes applies to the SGML document.
When key of is applied to data-attributes, the "@" (item) indexer is required.
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.
