Message
# Message validation failure : Invalid xsi&colon.type attribute value.
Cannot override type <insert_2> with type <insert_1>.
Explanation
Element <insert_3> has an xsi&colon.type attribute with value <insert_1>, but type <insert_1> conflicts with the 'block' attribute on type <insert_2>.
Response
Modify the message so that the value of the xsi&colon.type attribute is valid.
Modify message set <insert_4> so that type <insert_1> is a valid substitution for type <insert_2>.
