Schema 0 or more

[sk]

For the following xml document, schema is going to be like the following
but i am not sure how I can define meta_attribute in the schema so that
meta_attribute can be 0 or more.

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="iims11526672557483110">
<xs:complexType>
<xs:sequence>
<xs:element name="iims11526672678667402">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:maxLength value="50">
</xs:maxLength></xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="iims11526672818165646">
<xs:simpleType>
<xs:restriction base="xs:integer">
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
