Can relaxng specify an unordered set of elements with the same name but different attributes?

Im working on automation testing an API that accepts and returns XML, so I want to translate as much as possible the documented returned API data into the schema. I chose RelaxNG for this task based on ease of use and training.

Before throwing all the information, here is the question:

Is it possible to describe an "unordered set of elements with the same name but with different attributes"?

Here is an example of an object that I am having problems describing:

<item>
    <id>d395136e-d060-4a6e-887c-c0337dd7ad09</id>
    <name>The item has a name</name>
    <link rel="self" type="type1" href="url" />
    <link rel="download" type="type2" href="url" />
    <link rel="relatedData" type="type3" href="url" />
</item>

Link objects are the bit I hung up on. Here is the problem:

  • The order of the elements inside the element is not guaranteed, so I am trying to put all the elements in a structure <interleave>.
  • <item> <link>, (.. <item> "self", "" "relatedData" )).
  • , .

:

<element name="item">
    <interleave>
        <element name="id"><text/></element>
        <element name="name"><text/></element>
        <ref name="selfLink"/>
        <ref name="launchLink"/>
        <ref name="thumbnailLink"/>
    </interleave>
</element>

'link' :

 <define name="selfLink">
 <element name="link">
     <attribute name="href"><text/></attribute>
     <attribute name="rel"><value>self</value></attribute>
     <attribute name="type"><value>type1</value></attribute>
 </element>
 </define>
