FortiManager 5.4.1 XML API - 'ecprof' element meaning?

Hi there,

Does anybody know what exactly is meant by the 'ecprof' element in FortiManager's XML API WSDL?

What sort of data does it expect?

It is a required element for many messages, for example:

<xs:complexType name="DvmdbAdomPath">
    <xs:sequence>
      <xs:element name="ecprof" minOccurs="1" maxOccurs="1" type="xs:string" />
      <xs:element name="adom" minOccurs="0" maxOccurs="1" type="xs:string" />
      <xs:element name="option" minOccurs="0" maxOccurs="1" type="xs:string" />
    </xs:sequence>
</xs:complexType>
