SAPcat XML (CCM): Read-Only indicator

Hi all,

By loading an SAPcat XML (SAP XML Format for CatalogueUpdateNotification) schema, we can set indicators/flags for characteristics, e.g. Required, Relevant for Text Search, etc.

I know four out of five characteristic indicator tags that are included with SAPcat XML:

<MultipleValueIndicator>

<TextSearchableIndicator>

<ParametricSearchableIndicator>

<ValuationRequiredIndicator>

Does anyone know the tag for the Read-Only flag? Or can someone confirm that this flag is missing from SAPcat XML (which is what I suspect)?

Cheers,

Serguei
