title: <xs:any> and matching wildcard error
body: <p>Goal: create a complexType that allows element "skip" to contain any element, any number of times, in any order and validates my xml without error.</p>
  
  <p>Schema: skip.xsd </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;

    elementFormDefault="qualified"
    &gt;
  
    &lt;xs:complexType name="skip"&gt;
      &lt;xs:sequence&gt;
        &lt;xs:any minOccurs="1"

      &lt;/xs:sequence&gt;
    &lt;/xs:complexType&gt;

  <p>I import skip.xsd into my main.xsd</p>

  <p>I need to validate xml that can have the form:</p>
  
  <pre><code>&lt;skip&gt;
     &lt;anyelement1&gt;&lt;/anyelement1&gt;
     &lt;anyelement2&gt;&lt;/anyelement2&gt;
     &lt;anyelementN&gt;&lt;/anyelementN&gt;
  &lt;/skip&gt;
  </code></pre>
  
  <p>Problem: Error when validating; "cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for 
   element 'anyelement1' "</p>
