KERML — Documentation of features in Transfers library model is wrong

The Kernel Standard Library model for Transfers includes the following features, documented in subclauses of 9.2.7.2:

• 9.2.7.2.4 flowTransfers
• 9.2.7.2.5 flowTransfersBefore
• 9.2.7.2.7 messageTransfers
• 9.2.7.2.11 transfers
• 9.2.7.2.12 transfersBefore

In all these cases, the "Element" kind is documented simply as "Feature". However, in the normative Transfers.kerml file, all of these features are actually declared as steps.
