@jmarkmurphy, I believe that possibly you happen to be unfamiliar Along with the expression "properly-shaped" remaining a technical jargon time period to confer with the requirement to your standards of XML and XHTML that each one tags needs to have closing tags and need to be nested in the right purchase.
Some systems that create HTML can be based upon XML turbines, and thus don't have the chance to output just a bare tag; if you're making use of such a method, It can be fantastic to implement , It is just not required in case you need not do it.
To distinct up confusion: Putting an area prior to the slash is not necessary in HTML5 and isn't going to make any difference to how the website page is rendered (if any individual can cite an example I am going to retract this, but I don't think It is really correct - but IE html 5 game certainly does many other odd issues with all types of tags).
Old Netscape constantly needed the " /" Area before the slash or it failed. Who cares about previous browsers, correct? But its yet one more scenario for my Edition I continue to like :)

HTML is very lenient in this regard, and there's no this sort of rule. So in HTML vacant nodes like and many others are composed with no closing forward slash.
and do not satisfy the requirements of XML and XHTML simply because they don't have closing tags, eg: or are valid, just isn't valid XHTML or XML. HTML, obviously, doesn't have the very well-shaped necessity so and they are valid in HTML only.
The excellent validator at is absolutely handy for examining what's valid (Even though I am not sure you could trust in it to also Look at content material-style).
You shouldn't serve it with the XML declaration if working with textual content/html, although the content material could be normally valid XML (e.g. created from something that outputs XML, like XSLT output or an object that serializes to XML).
