Hi RyanStecken-9661,

It is not clear what XSD your using: XSD 1.0 or XSD 1.1
I assumed that it is XSD 1.0

Here is an XSD for your XML file:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" targetNamespace="http://meinnamespace.meinefirma.de/" xmlns:ns1="http://meinnamespace.meinefirma.de/">
  <xs:element name="school">
    <xs:complexType mixed="true">
      <xs:choice minOccurs="0" maxOccurs="unbounded">
        <xs:element ref="ns1:classroom"/>
        <xs:element ref="ns1:schoolname"/>
      </xs:choice>
    </xs:complexType>
  </xs:element>
  <xs:element name="classroom">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="ns1:classId"/>
        <xs:element ref="ns1:classname"/>
        <xs:element ref="ns1:student"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="classId" type="xs:integer"/>
  <xs:element name="classname" type="xs:string"/>
  <xs:element name="student">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="ns1:studentId"/>
        <xs:element ref="ns1:firstname"/>
        <xs:element ref="ns1:lastname"/>
        <xs:element ref="ns1:grade"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:element name="studentId" type="xs:integer"/>
  <xs:element name="firstname" type="xs:string"/>
  <xs:element name="lastname" type="xs:string"/>
  <xs:element name="grade" type="xs:integer"/>
  <xs:element name="schoolname" type="xs:string"/>
</xs:schema>
