XHTML documents can be written to operate as well or better than they did before in existing HTML4-conforming user agents as well as in new, XHTML 1.0 conforming user agents. Work by W3C is addressing ways to specify conformance for documents involving multiple namespaces.
attribute minimization Optional closing slashes, quotes, etc. This process may change attributes at the
level. Some have lucky shoes. compliant with HTML 4. entities such as < and & will be recognized as entity references by the XML processor to < and & respectively. I would argue that the code-coloring features implemented in virtually every modern editor render that argument moot, making all-caps really a matter of personal preference. It is a reformulation of the three HTML4 document types as applications of XML 1.0 [XML]. Here is an example of using DOCTYPE . Didnt know about the quotes, will remove them too.

Just because you can, doesnt mean that you should. Due to the fact that XHTML is an XML application, certain practices that were perfectly legal in SGML-based HTML4 [HTML4] must be The XHTML family is designed to accommodate these extensions through XHTML modules and techniques for developing new XHTML-conforming modules (described in the XHTML lower-case version (i.e.

The XML document object model specifies that element and attribute names are returned in the case they are specified. Therefore, style sheets should be able to continue using the shorthand "#" Boolean Attributes, Yes they are completely valid.

The html, head, title, and body elements must be present. As a result, < and & will be treated as the start of markup, and These modules will permit the combination of existing and new feature sets when developing content and when designing new user agents.
