XSD Text-only

This lesson is part of XML · All levels

Summary

Text-based elements that still require attributes should use <xs:simpleContent> within <xs:complexType>. Since simpleContent must not contain elements, it can only be <xs:extension> or <xs:restriction> that lower the text type such as xs:string or xs:decimal. This pattern is suitable for unit-type values, such as prices accompanied by currency attributes.

Key points

SimpleContent can only contain an extension or restriction
Extension base="xs:decimal" uses the text type and then adds the attribute
There should be no child element in simpleContent
Restriction is used to limit the value of a text, for example by enumeration
Attributes declared in such an extension or restriction
