Delete
The <Delete> element removes the current field or attribute from the document metadata.
Operations are not allowed to follow as siblings of the <Delete> element, because the delete operation invalidates the context field or attribute.
The following example deletes the field "myField" and the attribute "myAttributeToDelete".
<FieldStandardization>
<Field name="myField">
<Delete />
</Field>
<Field name="myOtherField">
<Attribute name="myAttributeToDelete">
<Delete />
</Attribute>
</Field>
