9. What about the need for end tags?
Remember that XHTML is an XML application.
Have a look at the markup fragments in the following table.
| Markup |
Comments |
<part-number>273</part-number>
wheel |
Invalid XML |
<part-number>273</part-number>
<part-type>wheel</part-type> |
Well-formed XML |
<h1>Introduction</h1>
Welcome to this document on XHTML. |
Valid HTML but invalid XHTML |
<h1>Introduction</h1>
<p>Welcome to this document on XHTML.</p> |
Valid HTML and well-formed XHTML |
Since XML documents can use arbitrary elements an XML application cannot know how the document is structured. Web browsers, however, do know something about the document structure. For example, text that occurs immediately after a heading is normally assumed to be part of a paragraph, and a <p> element is assumed. XML applications can't make such assumptions, so more rigourous markup is required.
