| - | Introduction | + | ==== Embedded RDF ==== |
| This document describes how a subset of RDF can be embedded into XHTML or HTML by using common idioms and attributes. No new elements or attributes have been invented and the usages of the HTML attributes are within normal bounds. This scheme is designed to work with CSS and other HTML support technologies. | This document describes how a subset of RDF can be embedded into XHTML or HTML by using common idioms and attributes.

| - | Embeddable RDF | + | === Embeddable RDF === |
| The subset of RDF that is used in this embedding scheme is called HTML Embeddable RDF. It allows some very important parts of the RDF model to be embedded but does not attempt to extend this to the full RDF model. This is very deliberate. Other attempts at embedding RDF in HTML have required the introduction of new syntax to express all the various RDF concepts. | The subset of RDF that is used in this embedding scheme is called HTML Embeddable RDF.
