Is there any pros to use HTML 5 doctype `<!DOCTYPE html>` even if i'm not using any new HTML 5 tag?

Is there any pros to use HTML 5 doctype <!DOCTYPE html> even if i'm not using any new HTML 5 tag? Is there any benefit to replace XHTML doctype with HTML 5 doctype even if i'm not using any new HTML 5 tag?

or in new projects which i'm going to start?

or it can create problems in any type of functionality if i 'm using any thing XML related with my site

or using HTML 5 can create with any A-Grade browser? IS it supported in all desktop and mobile browsers.

or for right now it's good to stick with XHTML Doctype till 2015?

It will surely break at least one old browser out there, so I recommend not using HTML 5 unless your page is actually HTML 5.

Also, XHTML and HTML 5 are not strictly compatible.

no it's compatible < /> self closing tag is also acceptable in HTML 5

Yes, but I mean is HTML 5 compatible with XHTML Strict? As far as I've seen HTML 5 is not some super-set of XHTML, they have incompatibilities.

You may be interested to check out John Resig's blog post on this topic (the founder of jQuery):

What's nice about this new DOCTYPE, especially, is that all current browsers (IE, FF, Opera, Safari) will look at it and switch the content into standards mode - even though they don't implement HTML5. This means that you could start writing your web pages using HTML5 today and have them last for a very, very, long time.

Any reason not to start using the HTML 5 doctype?

Slightly less typing.

That's about it.

I wouldn't use the HTML5 doctype yet. With this doctype you're stating that your document conforms to a specification that is still a moving target. IMO: wait until the spec is finished and the validation process tied down.
