    parser bug on misformed namespace attributes
    
    For https://bugzilla.gnome.org/show_bug.cgi?id=672539
    Reported by Axel Miller <axel.miller@ppi.de>
    
    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=""/>
                  ^
    [...]

    To build on an Unixised setup:
       ./configure ; make ; make install
    To build on Windows:
       see instructions on win32/Readme.txt
    
    To assert build quality:
       on an Unixised setup:
          run make tests
       otherwise:
           There is 3 standalone tools runtest.c runsuite.c testapi.c, which
           should compile as part of the build or as any application would.
           Launch them from this directory to get results, runtest checks 
           the proper functionning of libxml2 main APIs while testapi does
           a full coverage check. Report failures to the list.
