reviewed in call - agree that changes are needed.
the selection list has three options , pick from a list , enter something or no choice. the text should be updated as needed

In an earlier version we had in clause 6.8.1 the following text:

The SelectionListType, as defined in OPC 10000-5, is used in many places, where modification is possibly mandated. This type allows providing values selectable from the Selections and an optional description using SelectionDescriptions.
If the generator set the optional RestrictToList to value True, only values from the list can be applied to the element. With this, the generator of the data may restrict changes by supplying a list of accepted values. As an example, the PublishingInterval could be restricted to the values 2 ms, 4 ms, and 17 ms by adding these values to Selections and set RestrictToList to True.
Setting RestrictToList to value False allows in opposite to apply any value to the element.

Now the text is reduced to:

The SelectionListType (see OPC 10000-5) is used to indicate where support for modifications is required by this specification. The possible selections, and if entry is allowed, is provided by the engineering tool that generated the ConnectionConfigurationSet. The selections may include an optional description.

Updated 6.8.1 as follows:

The SelectionListType (see OPC 10000-5) is used to indicate where support for modifications is required by this specification. This type allows the engineering tool to provide a list of Selections and an optional description of them.
If the engineering tool sets the optional RestrictToList to True, a Client changing the Variable is restricted to the provided Selections. If set to False or missing, a Client may change the Variable to any value including one of the Selections.
As an example, an engineering tool may restrict the PublishingInterval to the values 2 ms, 4 ms, and 8 ms by adding these values to Selections and setting RestrictToList to True.

Cross-referenced the description in 6.8.1 from clauses 9.2.2 and 9.2.3 and updated text there.

updated 6.8.1, 9.2.2, and 9.3.2
