One problem about XSD

["Juny Yin" <xujun.yin@gmail.com>]

Hi, xml-dev experts:

 

   Now I have one problem about XSD as the following:

I want to define the contents model of an element, For example the element is <EleParent> and currently it

has four children elements:<a>,<b>,<c>,<d>. these children elements can appear in any order under  <EleParent>.

For extensibility any other children elements can be added to <EleParent> in any order. 

 

How can I write the schema for this requirement?

Who can give me the answer?

 

Thanks a lot.
 

Best regards.
