Answer 2

<abstract-schema-name>PreDocs</abstract-schema-name>中是 PreDocs                <cmr-field>
                    <description>preDocs</description>
                    <cmr-field-name>docs</cmr-field-name>
                    <cmr-field-type>java.util.Collection</cmr-field-type>
                </cmr-field>中是 preDocs

Answer 3

去掉PreDocs的<field-name>predocTypeId</field-name>，该字段已被用作cmr,就不能作cmp.
