Description:
------------
SimpleXML allows the creation of attributes containing white spaces in the name. This violates the XML specs [1].

* reported by Thiago Toledo during PHP Test Fest 2009 (Rio UG).

[1] http://www.w3.org/TR/2006/REC-xml11-20060816/#NT-NameChar

Reproduce code:
---------------
<?php
    $xmlExample = "<?xml version='1.0' standalone='yes'?><allNodes></allNodes>";
    $myXML = new SimpleXMLElement($xmlExample);
    $myXML->addAttribute('Basic Attribute','Basic Attribute Content');
    echo $myXML->asXML();
?>

Expected result:
----------------
Warning: Wrong character for XML attribute name

Actual result:
--------------
<?xml version="1.0" standalone="yes"?>
<allNodes Basic Attribute="Basic Attribute Content"/>

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

I think its more along the lines of a libxml2 bug then PHP's since 
attribute creation is done by simply calling the libxml API. PHP cannot 
perform validation on XML.
