Some editor seems to have swapped the position of baseURI and description elements within smlif:identityType. This must be accidental change since I do not recall any WG decision leading to this change. This breaks all existing SML-IF models. 

Proposal:
Change the definition of identityType:

from:
  <xs:complexType name="identityType">
    <xs:sequence>
      <xs:element name="name" type="smlif:uriType"/>
      <xs:element name="version" type="smlif:tokenType" minOccurs="0"/>
      <xs:element name="displayName" type="smlif:displayType" minOccurs="0"/>
      <xs:element name="description" type="smlif:displayType" minOccurs="0"/>
      <xs:element name="baseURI" type="smlif:uriType" minOccurs="0"/>
      <xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
    <xs:anyAttribute namespace="##other" processContents="lax"/>
  </xs:complexType>

to:
  <xs:complexType name="identityType">
    <xs:sequence>
      <xs:element name="name" type="smlif:uriType"/>
      <xs:element name="version" type="smlif:tokenType" minOccurs="0"/>
      <xs:element name="displayName" type="smlif:displayType" minOccurs="0"/>
      <xs:element name="baseURI" type="smlif:uriType" minOccurs="0"/>
      <xs:element name="description" type="smlif:displayType" minOccurs="0"/>
      <xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
    </xs:sequence>
    <xs:anyAttribute namespace="##other" processContents="lax"/>
  </xs:complexType>
