Status: Wont fix

Changing this would break some long standing BC. The problem is really
in setting the attribute value. The workaround for this is to use
something like htmlspecialchars when setting a DOMAttr->value using
another DOMAttr->value

Description:
------------
When you fetch the "value" field of a DOMAttribute, it seems to unescape
any HTML (or perhaps XML?) entities present. However, when you set it,
it does not get escaped. In other words, if you do "$attr->value =
$attr->value" (which really should be a no-op!) as in the example below,
you will get errors if it happened to contain &.
Verified with PHP 5.2.6 and 5.3.0 snap (2008-02-28).
Reproduce code:
---------------
<?php
$doc = new DOMDocument;
$doc->loadXML('<html><element /></html>');
$elem = $doc->documentElement->firstChild;
$attr = $doc->createAttribute("foo");
$attr->value = "foo&bar";
$attr->value = $attr->value;
$elem->appendChild($attr);
print $doc->saveXML();
?>
Expected result:
----------------
<?xml version="1.0"?>
<html><element foo="foo&bar"/></html>
Actual result:
--------------
Warning: main(): unterminated entity reference bar in
/home/sesse/test3.php on line 8
<?xml version="1.0"?>
<html><element foo="foo"/></html>
