Hello Daniel,

 Yesterday i speak with some other people in public XML forums about
my question and they tell me, that your position seems to be more
correct then mine, but this thing is not clearly specified into any
available specification.
 But i still have 2 questions about this topic and one of them
confuses me a bit, can you please comment it?

1. If current behaviour of libxml2 is expected - is it mean, that i
should manually perform analize of a text, i want to set as attribute
value for entities, split it up in parts and construct actual
attribute value as set of Text and EntityReference objects?

 So, it mean that authors of PHP bindings for libxml2 just use wrong
API call for setting attribute value? If so, can you please point me
to a function, which should be used for setting attribute value
instead of xmlSetProp() ? So I will be able to write proper bugreport
for PHP.

<?xml version="1.0"?><root a="a&amp;amp;b">a&amp;b</root>

 Can you please explain, why "&amp;" being set in attribute value is
quoted while same "&amp;" being set as node value is treated as entity

 It looks like this behaviour was changed sometime in the past... At
least following Perl example:

use XML::LibXML;
use strict;
my $parser = XML::LibXML->new() or die;
my $doc    = $parser->parse_string('<'.'?xml version="1.0"?'.'><root/>');
my $root   = $doc->documentElement();
$root->setAttribute ('a','a&amp;b');
$root->appendText   ('a&amp;b');
print $doc->toString; 

 produces following output:

<?xml version="1.0"?>
<root a="a&amp;amp;b">a&amp;amp;b</root>

 with XML::LibXML v1.53, libxml v1.8.17.
