Answer 1

I think you need to use character entities. & for the ampersand, for example, and < for the less. XML Schema is XML, and you have to live with XML rules. Expanding your question to actually show us the schema context would help.

Answer 2

You want define a type that extends string and add a restriction with a pattern Something like

<xs:element name="your_element">
  <xs:simpleType>
    <xs:restriction base="xs:string">
      <xs:pattern value="[a-zA-Z0-9_.' !@#$%^*()_+={}|/:;,>?/`~ ]"/>
    </xs:restriction>
  </xs:simpleType>
</xs:element>
