This is not necessarily true. If the schema requires the child
element, then yes. However what about a schema that allows but does
not require an element? That's quite common in practice. In a DTD
it's the effect of elementName? or elementName* in a <!ELEMENT>
declaration; and of course not all documents have DTDs or schemas.
