HTML does normally allow to have no spaces between attributes when attributes have values and those values are quoted.
Example (Reference/Source):
In HTML-documents no White Spaces between Attributes are needed.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>no attribute space</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
<p class="CLASS"title='TITLE'></p>
</body>
</html>
See the third-last line:
<p class="CLASS"title='TITLE'></p>
^^
Now using such HTML chunk changing the doctype to HTML 5 (<!DOCTYPE HTML>), makes the experimental W3C HTML 5 conformance checker give an error exactly there telling me:
Validation Output: 1 Error
Error Line 9, Column 22: No space between attributes.
<p class="CLASS"title='TITLE'></p> ^
So I thought that HTML 5 is backwards compatible to how browsers deal with HTML in reality and browsers AFAIK deal with this well. So I'm a bit puzzeled at least. I also have problems to decipher the (somewhat needlessly) compilcated HTML 5 specs to be precise at this point because what I did find (W3C again, see http://www.w3.org/TR/html-markup/syntax.html#syntax-attributes) it's not saying that this is (may nor must) be an error.

You are reading a discontinued, non-normative reference. If you look at the definition of the start tag in the specification (which is normative) it says:
Then, the start tag may have a number of attributes, the syntax for which is described below. Attributes must be separated from each other by one or more space characters.
So I thought that HTML 5 is backwards compatible to how browsers deal with HTML in reality and browsers AFAIK deal with this well.
Being compatible with real world markup is a design goal, but lots of things have been obsoleted and leaving out the space between attributes is something that almost never occurs intentionally.
