How to define an element in an xsd which has parent element in the child

How to define an element in an xsd which has parent element in the child?

Here is an example:

<score seq="1" type="test" numeric="23">
    <option lbound="0" ubound="">
        <score seq="1" type="app" numeric="575">
            <option lbound="" ubound="0">0</option>
        </score>
    </option>
</score>

Here's an option for any level of nesting...

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
    <xs:element name="score">
        <xs:complexType>
            <xs:sequence>
                <xs:element minOccurs="0" maxOccurs="unbounded" ref="option"/>
                <xs:element minOccurs="0" maxOccurs="unbounded" ref="ignore"/>
            </xs:sequence>
            <xs:attribute name="numeric" use="optional" type="xs:integer"/>
            <xs:attribute name="seq" use="required" type="xs:integer"/>
            <xs:attribute name="type" use="required" type="xs:NCName"/>
        </xs:complexType>
    </xs:element>
    <xs:element name="option">
        <xs:complexType mixed="true">
            <xs:sequence>
                <xs:element minOccurs="0" maxOccurs="unbounded" ref="score"/>
            </xs:sequence>
            <xs:attribute name="id" use="optional"/>
            <xs:attribute name="lbound" use="optional"/>
            <xs:attribute name="ubound" use="optional"/>
        </xs:complexType>
    </xs:element>
    <xs:element name="ignore"/>
</xs:schema>

This works for both examples you've given:

Example 1

<score seq="1" type="test" numeric="23">
    <option lbound="0" ubound="">
        <score seq="1" type="app" numeric="575">
            <option lbound="" ubound="0">0</option>
        </score>
    </option>
</score>

Example 2 (from comment)

<score seq="1" type="IN">
    <option id="1">10</option>
    <ignore/>
</score>
