Show me sample XML for this XSD?

Question

I am trying to write valid XML for this schema:

<xsd:complexType name="resourceType">
    <annotation xmlns="http://www.w3.org/2001/XMLSchema">
        <documentation>
            A resource root within a deployment.
        </documentation>
    </annotation>
    <xsd:all>
        <xsd:element name="filter" type="filterType" minOccurs="0">
            <annotation xmlns="http://www.w3.org/2001/XMLSchema">
                <documentation>
                    A path filter specification for this resource root (optional). By default all paths are accepted.
                </documentation>
            </annotation>
        </xsd:element>
    </xsd:all>
    <xsd:attribute name="name" type="xsd:string" use="optional">
        <annotation xmlns="http://www.w3.org/2001/XMLSchema">
            <documentation>
                The name of this resource root (optional). If not specified, defaults to the value of the path
                attribute.
            </documentation>
        </annotation>
    </xsd:attribute>
    <xsd:attribute name="path" type="xsd:string" use="required">
        <annotation xmlns="http://www.w3.org/2001/XMLSchema">
            <documentation>
                The path of this resource root, relative to the path in which the module.xml file is found.
            </documentation>
        </annotation>
    </xsd:attribute>
</xsd:complexType>

I am new to XML and XSD, and I will be grateful for little help: What would be an example XML document that would be valid according to this XSD?

There are two issues that prevent any XML from being valid against your XSD as provided:

1. The XSD includes a reference to an undefined type, filterType.
2. The XSD specifies no root element.

By replacing filterType with xsd:string and adding a root element, r of type equal to the top-level complexType in your XSD, then this modified XSD,

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="r" type="resourceType"/>
  <xsd:complexType name="resourceType">
    <annotation xmlns="http://www.w3.org/2001/XMLSchema">
      <documentation>
        A resource root within a deployment.
      </documentation>
    </annotation>
    <xsd:all>
      <xsd:element name="filter" type="xsd:string" minOccurs="0">
        <annotation xmlns="http://www.w3.org/2001/XMLSchema">
          <documentation>
            A path filter specification for this resource root
            (optional). By default all paths are accepted.
          </documentation>
        </annotation>
      </xsd:element>
    </xsd:all>
    <xsd:attribute name="name" type="xsd:string" use="optional">
      <annotation xmlns="http://www.w3.org/2001/XMLSchema">
        <documentation>
          The name of this resource root (optional). If not specified,
          defaults to the value of the path attribute.
        </documentation>
      </annotation>
    </xsd:attribute>
    <xsd:attribute name="path" type="xsd:string" use="required">
      <annotation xmlns="http://www.w3.org/2001/XMLSchema">
        <documentation>
          The path of this resource root, relative to the path in
          which the module.xml file is found.
        </documentation>
      </annotation>
    </xsd:attribute>
  </xsd:complexType>
</xsd:schema>

would successfully validate the following XML, for example:

<?xml version="1.0" encoding="UTF-8"?>
<r path="">
  <filter/>
</r>
