New Comment:
Just adding the namespace declaration as normal attribute is not
supported. You should instead create the saml:Assertion element
as node with associated namespace; see <https://3v4l.org/lsIVL>
for the correct code.

Description:
------------
The test script perform the same operation twice but the result (the last two lines) are different
depending on if the XML has been created dynamically or loaded (in this case by storing the
dynamically created XML and (re)loading it).
You may reorder the createAttribute lines as you want but the last two lines will always be the same
- the last line being correct.
Test script:
---------------
$xml = new DOMDocument();
$element = $xml->createElement('saml:Assertion');
$xml_saml_assertion = $xml->appendChild($element);
$attribute = $xml->createAttribute('id');
$attribute->value = 'IDCard';
$xml_saml_assertion->appendChild($attribute);
$attribute = $xml->createAttribute('xmlns:saml');
$attribute->value = 'urn:oasis:names:tc:SAML:2.0:assertion';
$xml_saml_assertion->appendChild($attribute);
$attribute = $xml->createAttribute('Version');
$attribute->value = '2.0';
$xml_saml_assertion->appendChild($attribute);
print("<pre>" . htmlentities($xml->saveXML()) .
"</pre><br>\n");
print("<pre>" . htmlentities($xml->C14N(TRUE)) .
"</pre><br>\n");
$xml->loadXML($xml->saveXML());
print("<pre>" . htmlentities($xml->C14N(TRUE)) .
"</pre><br>\n");
Expected result:
----------------
<saml:Assertion xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
Version="2.0" id="IDCard"></saml:Assertion>
Actual result:
--------------
<saml:Assertion Version="2.0" id="IDCard"
xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"></saml:Assertion>
