The expression void components is used to designate aspects that has to be vacant. These specifications only utilize to the HTML syntax. In XHTML, all such things are handled as normal elements, but need to be marked up as empty components.

We can only hope that in the future Web, we go clear of non-public vendor-implemented benchmarks and go back to strong, trustworthy, verified markup that parses a lot quicker, moves data in excess of the wires a lot quicker, and make our long term Net a more standardized medium using XML.

It truly is "very good coding observe" for ALL Website Builders to help keep using reliable markup techniques that follow XML, together with coding in all lower case, quoted attributes, escaped XML people, etc. etcetera. Why? Sooner or later if you have to swap to XML details you automatically code and Imagine in XML.
This Suggestion like its predecessor gives an updated steady guidebook to what is HTML. In the past year There's been a major cleanup with the specification.
