Any element with specific attributes and children

Hi,
 
I am trying to use the <any> element, but with specific attributes and
specific children. I'd like to demonstrate this by using a RelaxNG
Compact definition:
 
----------------------
start = myRoot
 
myRoot = element MyRoot
{
 myRootChild *
}
 
myRootChild = element *
{
 myRootChildAttributes
 , myRootChildChildren
}
 
myRootChildAttributes =
(
 attribute attr1 {string}
 , attribute attr2 {string}
)
 
myRootChildChildren =
(
 specificElement *
)
 
specificElement = element Specific
{
 myRootChild *
}
----------------------
 
The <any> element in the XML Schema looks as follows
 
----------------------
<xs:group name="myRootChild">
    <xs:sequence>
      <xs:any processContents="skip"/>
    </xs:sequence>
</xs:group>
----------------------
  
I am unable to specify that the <any> element must contain certain
specific attributes (attr1 and attr2) and certain children (Specific).
Is this possible at all in XML Schema?
 
Regards,
Metin Solmaz
