XML data does not comply with schema & Malformed XML data

the second issue (Malformed XML data) has been solved:

F5 added the internal parameter "allowXSIRename" that enables you to allow using a namespace prefix different from "xsi" for ";. Set this parameter to 1 to allow different names for the xsi prefix. The default value is 0 (disallow).

This WSDL document is not using the common prefix, by default the BIG-IP won't accept documents using anything other than the common prefix.

If you can't change the application to use the common prefix we can change this behavior on the BIG-IP using this command:

/usr/share/ts/bin/add_del_internal add allowXSIRename 1 bigstart restart asm

bigstart restart asm

tmsh save sys config

This will restart BIG-IP and cause a failover so please perform this in a maintenance window
