Solução

Lets go line by line

<!DOCTYPE html> - HTML5 Doctype

<html xmlns="http://www.w3.org/1999/xhtml"> - Refer here

<head> - Document head element

<meta name="Generator" content="some info here ..." /> Description of the program you used to create the HTML document

<meta charset="utf-8" /> - Document Character Encoding, Good read

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> Read Here And Here

I would've certainly wrote a big fat description for each but realized that these were already asked in different questions, so thought to link them instead of repeating the same thing here again.

Outras dicas

The code snippet is mostly the start of an HTML5 document in XHTML (XML) serialization, sometimes confusingly called XHTML5.

It is not a conforming document, however; the current HTML5 CR does not allow the attribute http-equiv="X-UA-Compatible" (on rather formal grounds, but still).

The doctype belongs to HTML5 Doctype definition.

So the rest of the document should be bases on HTML5
