Consider the following start-tag:
<x xmlns=""version="">

The start-tag does not conform to the rule

[40]       STag       ::=       '<' Name (S Attribute)* S? '>'

since there is no whitespace in front of the attribute "version".

Thus, libxml2 should reject the start-tag.
But it doesn't:

$ echo '<x xmlns=""version=""/>' | xmllint -
<?xml version="1.0"?>
<x xmlns="" version=""/>

The error seems to happen only if there is a namespace declaration in
front of
the attribute. A missing whitespace between other attributes is handled
correctly:

$ echo '<x someattr=""version=""/>' | xmllint -
-:1: parser error : attributes construct error
<x someattr=""version=""/>
              ^
