Multiple ATTLIST declarations for a attribute!

[Vivek Saxena]

Hi,
As per my understanding, if I have two "ATTLIST" declarations (for same attribute) for a element then parser is supposed to ignore second one and should use first one.
But i am trying following in XMLSpy and it seems confusing.
if I include second ATTLIST in same file for same element then it takes second value.

For example:
DTD File

<?xml version="1.0" encoding="UTF-8"?>
<!ELEMENT person (name,age,sex)>
<!ELEMENT name (#PCDATA)>
<!ELEMENT age (#PCDATA)>
<!ATTLIST name lastname CDATA #FIXED "saxena">
<!ATTLIST name lastname CDATA #FIXED "singh">

xml file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE person SYSTEM "C:\Documents and Settings\viveks\Working\xml\test.dtd" [
<!ELEMENT sex (#PCDATA)>
]>
<person>
<name lastname="singh">viveks</name>
<age>26</age>
<sex>M</sex>
</person>

Above XML file is valid as per XMLSpy but i don't think so. it should take the first vale for attribute 'lastnma' and it should be "saxena".
Please help me here.
Thanks
