[cdlans]

The XML schema for MTConnect v1.3.1, implements elements with the abbreviation "ID" in the name with the wrong capitalization.

The MTConnect Standard (v1.3.1) Part 3, section 5.6.3 defines the following Event XML elements:

• OperatorID
• PalletID
• PartID
• ToolAssetID
• WorkholdingID

However, in the XML schema, they are implemented as:

• OperatorId
• PalletId
• PartId
• ToolAssetId
• WorkholdingId
