===============================================================
REVISION HISTORY FOR THE SCL XSD FILES, AFTER RELEASE 1.0
FROM June 1, 2004.
===============================================================

CF 2004/06/04:
  - in SCL_*.xsd: updated the annotation and the version of
    the XSD files.
  - (T5) in SCL_Enums.xsd: added "Oper", "SBO", "SBOw", and "Cancel"
    to the allowed values for "tPredefinedAttributeNameEnum" (Tissue #5).

CF 2004/06/14:
  - in SCL_*.xsd: only changed files have a new version, including
    SCL.xsd.
  - (T9) in SCL_IED.xsd: attribute "datSet" of "tControl" made optional. Rationale:
    if provided, the identity constraints will ensure that it exists (in the
    same LN). If not provided, it means that there is no data set. Remark: do
    not use the empty string to indicate that there is no data set associated
    with the control block.

CF 2005/02/14:
  - (T17) in SCL_IED.xsd: type of attribute Name of tSDI set to tAttributeNameEnum
  - (T17) in SCL_IED.xsd: type of attribute Name of tDAI set to tAttributeNameEnum
    (should be the same as for attribute Name of DA in the data
    type templates section)

CF 2005/07/27:
  - (T1, T2) in SCL_Communication.xsd: corrected Tissue Entry #1 (Syntax)
    for the pattern definition of tP_IP, tP_IP-SUBNET, tP_IP-GATEWAY.
    Changed from "[0-2]?\d{1,2}\.[0-2]?\d{1,2}\.[0-2]?\d{1,2}.[0-2]?\d{1,2}"
    to           "[0-2]?\d{1,2}\.[0-2]?\d{1,2}\.[0-2]?\d{1,2}\.[0-2]?\d{1,2}".
  - (T3) in Enumtypes.xml: Tissue Entry #3 (Missing ENUMs) added enums AutoRecSt,
    FltLoop, and PmpCtl. The values are those as defined in 7-4.
  - (T6) in SCL_IED.xsd: corrected Tissue Entry #6 (ReportControl/OptFields):
    removed attribute "segmentation" from agOptFields.
  - in SCL_DataTypeTemplates.xsd: renamed identity constraint uniqueDAorSDOInLDOType
    to uniqueDAorSDOInDOType.
  - in SCL_DataTypeTemplates.xsd: renamed identity constraint uniqueBDAInLDAType
    to uniqueBDAInDAType.
  - (T8)in Enumtypes.xml: Tissue Entry #8 (SIUnit enumeration for W): renamed
    EnumVal with ord 62 from W to Watts.
  - in ExampleFDIS.xml: inverted attributes type and xsi:type for P attributes
    so that XML Spy does not complain anymore (although this is valid).
  - in ExampleFDIS2.xml: inverted attributes type and xsi:type for P attributes
    so that XML Spy does not complain anymore (although this is valid).
  - in SCL_IED.xsd: (optional) attribute datSet of tControl is now of type
    tName, instead of tAnyName. If provided, it should not be empty.
  - (T10) in SCL_Enums.scl: Tissue Entry #10 (Base type for bitstring usage): added
    enumeration value "Check" to tPredefinedBasicTypeEnum.
  - (T15) in SCL_IED.xsd: corrected Tissue Entry #15 (bufOvfl in Schema?):
    removed attribute "bufOvfl" from agOptFields.
  - (T16) in SCL_IED.xsd: corrected Tissue Entry #16 (modify attribute missing):
    created new type tServiceWithMaxAndMaxAttributesAndModify, for ConfDataSet.
  - (T24) in SCL_Communication.xsd: corrected Tissue Entry #24 (wrong schema constraint):
    Added field "@ldInst" to the identity constraints uniqueGSEinConnectedAP and
    uniqueSMVinConnectedAP in tSubNetwork.

CF 2005/08/11:
  - SCL_BaseSimpleTypes.xsd: removed comments (xs:annotation).
  - (T18, T130) SCL_BaseSimpleTypes.xsd: added simple type tRestrLdName, for the name of a LD.
    It is restricted to alfanumeric (but starting with a letter), min 1 and max 64 char.
  - (T18, T130) SCL_IED.xsd: corrected Tissue #18, 130: LDevice element: optional attribute
    ldName added.
  - (T18) SCL_BaseSimpleTypes.xsd: (Tissue #18) tHeader: funcName restricted to "IEDName", and
    made optional with default value "IEDName".
  - (T5) in SCL_Enums.xsd: added "Check" to the allowed values for
    "tPredefinedAttributeNameEnum" (Tissue #5).
  - (T8) in SCL_Enums.xsd: tSIUnitEnum corrected (Tissue #8): phi instead theta, Watts introduced.
  - (T8) in Enumtypes.xsd: SIUnit corrected (Tissue #8): phi instead theta.
  - (T169) in Enumtypes.xsd: (Tissue #169) angid: order of Vother and Aother adapted to 7-3.
  - (T12) in SCL_IED.xsd: Tissue #12 - GSSE, GOOSE; type changed to tServiceWithMaxAndCLient;
    this type added.
  - *.xsd: new version set to 1.4.

WW 2005/08/15
  - SCL_Enums.xsd: added "VisString129" to "tPredefinedBasicTypeEnum" because of 7-3 modification
