Request #41326 Writing empty tags with Xmlwriter::WriteElement[ns]

Description:
------------
Currently Xmlwriter::WriteElement() and Xmlwriter::WriteElementNS() require the forth argument $content and are therefor not able to output empty tags. Someone has to use XmlWriter::startElement(); and XmlWriter::endElement(); to output an empty tag. That's a bit cumbersome.

It would be nice if $content could be made optional or set to null to output an empty tag. I know it's the documented behavior, that it always write a a full element tag and libxml2 does have the same behavior. Nevertheless it would be a nice addition to be able to write less code for a short tag.

Reproduce code:
---------------
<?php
$xml = new XmlWriter();
$xml->openMemory();
$xml->startDocument();
$xml->startElement('test');
$xml->writeElement('foo', null);
$xml->startElement('bar');
$xml->endElement('bar');
$xml->endElement();
echo $xml->outputMemory();
?>

Expected result:
----------------
<?xml version="1.0"?>
<test><foo/><bar/></test>

Actual result:
--------------
<?xml version="1.0"?>
<test><foo></foo><bar/></test>

Thank you for the report, and for helping us make PHP better.

Little notice about the final fix, there is now three cases:

$xml->writeElement('foo', '');
<foo></foo>

$xml->writeElement('foo', null);
<foo/>

$xml->writeElement('foo');
<foo/>

Doing it this way preserves BC while allowing the short form.
