how to make the order of elements in the DTD null n void

[Varun Suri <varunsuri@trade-india.com>]

  Hello,

I have defined a DTD with a set of xml's. These xml's have the elements 
defined in more that one order,
like
<!---------- a.xml------------>
<CompanyProfile>
    <Profile>
    ..........
    </Profile>
    <Promotion>
         ............
    </Promotion>
</CompanyProfile>

Another xml file has the order changed

<!-----------b.xml-------->
<CompanyProfile>
    <Promotion>
    .............
    </Promotion>
    <Profile>
    ..........
    </Profile>
</CompanyProfile>
The DTD for these files contains
<!ELEMENT CompanyProfile ( Profile?, Promotion?)>


 The problem im facing is that when i validate the xmls with the 
corresponding DTD, it throws an error in b.xml, which relates to the 
order of the elements Profile and Promotion.

Im using xmllint to validate the xml :

$xmllint --noout --valid a.xml

My questions is:
How can i override the order of elements (the elements are optional in 
nature as well) not to be checked with the corresponding DTD?
Ive used a XML schema to validate the xmls but doesnt work, since i cant 
have an ordered list ("all") have maxOccurs=unbounded

Thanks for you help in advance
