title: XML Schema- how to match any integer?
body: <p>I need to write a XML file which should conform to a schema. The schema enforces datatype of the element (happens to be process id on Linux) to be an integer. </p>
  
  <p>This fragment of the code passed the validation- </p>
  
  <pre><code>&lt;pid datatype="int"&gt;123&lt;/pid&gt;
  </code></pre>
  
  <p>However, I won't know "123" or the process id beforehand, as such, I want to write something like this- </p>
  
  <pre><code> &lt;pid datatype="int"&gt;*&lt;/pid&gt;
  </code></pre>
  
  <p>Obviously this doesn't work as * is seen as string as opposed to integer. </p>
  
  <p>My question is - is there a way I can enter a value <strong>in XML file</strong> which will pass the test?</p>
  
  <p>EDIT- here is the schema-
