This does not manifest in 5.3.8 on OS X 10.6.8, the '<!DOCTYPE' is not removed.
I'd post my test script and output but I keep getting the error "Please do not

Description:
------------
I guess this may not be a bug but I can find no information about how to import an XML with a DTD
declaration (<!DOCTYPE...) and have the resulting XML still contain the declaration when I use
the asXML method. All I get is the file with the declaration removed. I have tried LIBXML_DTDLOAD,
LIBXML_DTDATTR and they don't seem to help.
On a related note when I set an element using simplexml and it includes an '&' ans
part of an entity reference (i.e. &M;) it gets converted to '&'. How can I
stop that?
Test script:
---------------
$exptml= simplexml_load_file('http://chalk.coas.unf.edu/eureka/files/templates/tmpl_chm.xml');
echo $exptml->asXML();
Expected result:
----------------
<?xml version="1.0" encoding="UTF-8"?>
<!-- Example Chemical - ExptML v0.1 SJC 4/7/11 -->
<!DOCTYPE ExptML SYSTEM "http://chalk.coas.unf.edu/eureka/files/exptml/exptml_entities.dtd">
<chemical id="pid" xmlns="urn:exptml:schema:draft:0.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:unitsml="urn:oasis:names:tc:unitsml:schema:xsd:UnitsMLSchema-1.0"
xsi:schemaLocation="urn:exptml:schema:draft:0.1 http://chalk.coas.unf.edu/eureka/files/exptml/exptml_chemical.xsd"
version="0.1">
<name>Chemical name</name>
...
</chemical>
Actual result:
--------------
<?xml version="1.0" encoding="UTF-8"?>
<!-- Example Chemical - ExptML v0.1 SJC 4/7/11 -->
<chemical id="pid" xmlns="urn:exptml:schema:draft:0.1"
