There is no way to know when you're on a SimpleXMLElement, if there were a new namespace declared on current node. 

It's due to getDocNamespaces or getNamespaces returning xmlns status for all the document or document root only.

It's conform to what is described in the documentation but as user we may expect a different behavior.

Test script:
---------------
<?php
//phpinfo();

$x = new SimpleXMLElement(
'<?xml version="1.0" standalone="yes"?>
<people xmlns:p="http://example.org/p" >
    <person id="1" xmlns:t="http://example.org/t" >
		<name>John Doe</name>
	</person>
    <person id="2">Susie Q. Public</person>
    <o>
		<div>jdslkfjsldk jskdfjsmlkjfkldjkjflskj kljfslkjf sldk</div>
	</o>
</people>');
//echo '<pre>',$x->asXML(),'</pre>';
echo "\n<br>recursive: <br>\n";
//$tmp = $x->getNamespaces(true) ;
//var_dump($tmp);
$tmp = $x->getDocNamespaces(true) ;
var_dump($tmp);
echo "\n<br>\n";
//$tmp = $x->person[0]->getNamespaces(true) ;
//var_dump($tmp);
$tmp = $x->person[0]->getDocNamespaces(true) ;
var_dump($tmp);
echo "\n<br>\n";
//$tmp = $x->person[1]->getNamespaces(true) ;
//var_dump($tmp);
$tmp = $x->person[1]->getDocNamespaces(true) ;
var_dump($tmp);
*/
echo "\n<br>non recursive: <br>\n";
//$tmp = $x->getNamespaces(false) ;
//var_dump($tmp);
$tmp = $x->getDocNamespaces(false) ;
var_dump($tmp);
echo "\n<br>\n";
//$tmp = $x->person[0]->getNamespaces(false) ;
//var_dump($tmp);
$tmp = $x->person[0]->getDocNamespaces(false) ;
var_dump($tmp);
echo "\n<br>\n";
//$tmp = $x->person[1]->getNamespaces(false) ;
//var_dump($tmp);
$tmp = $x->person[1]->getDocNamespaces(false) ;
var_dump($tmp);



Expected result:
----------------
if we were able to provide namespace declare only on current node instead of root node, the function will provide the following result

recursive:
array(2) { ["p"]=> string(20) "http://example.org/p" ["t"]=> string(20) "http://example.org/t" }
array(1) { ["t"]=> string(20) "http://example.org/t" }
array(0) {  }
non recursive:
array(1) { ["p"]=> string(20) "http://example.org/p" }
array(1) { ["t"]=> string(20) "http://example.org/t" }
array(0) {  } 



Actual result:
--------------
recursive:
array(2) { ["p"]=> string(20) "http://example.org/p" ["t"]=> string(20) "http://example.org/t" }
array(2) { ["p"]=> string(20) "http://example.org/p" ["t"]=> string(20) "http://example.org/t" }
array(2) { ["p"]=> string(20) "http://example.org/p" ["t"]=> string(20) "http://example.org/t" }
non recursive:
array(1) { ["p"]=> string(20) "http://example.org/p" }
array(1) { ["p"]=> string(20) "http://example.org/p" }
array(1) { ["p"]=> string(20) "http://example.org/p" }
