Description:
------------
Now if you want to use DOMDocument::createAttribute

$domDocument = new DOMDocument('1.0', "UTF-8");
$domElement = $domDocument->createElement('field','some random data');
$domAttribute = $domDocument->createAttribute('name');

// Value for the created attribute
$domAttribute->value = 'attributevalue';

// Don't forget to append it to the element
$domElement->appendChild($domAttribute);

// Append it to the document itself
$domDocument->appendChild($domElement);


What I am suggesting is because DOMDocument::createAttribute returns
a new instance of class DOMAttr. And the DOMAttr class contructor accepts as params the name and the value of the attribute, so I suggest that createAttribute also accepts value as a param

$domDocument = new DOMDocument('1.0', "UTF-8");
$domElement = $domDocument->createElement('field','some random data');

// Create and set value for the attribute
$domAttribute = $domDocument->createAttribute('name', 'attributevalue');

// Don't forget to append it to the element
$domElement->appendChild($domAttribute);

// Append it to the document itself
$domDocument->appendChild($domElement);


---
Because this is possible

$domDocument = new DOMDocument('1.0', "UTF-8");
$domElement = $domDocument->createElement('field','some random data');

// Create and set value for the attribute
// Using the DOMAttr directly
$domAttribute = new \DOMAttr('name', 'attributevalue');

// Don't forget to append it to the element
$domElement->appendChild($domAttribute);

// Append it to the document itself
$domDocument->appendChild($domElement);
