Question: In a PSS server, when merging multiple device capability profiles with overlapping attributes, how are attribute values resolved if no specific resolution rules are provided in the schema?
Option 1: The earliest occurrence of the attribute value takes precedence over all subsequent ones.
Option 2: Attribute values from previous profiles are always overridden by those from later profiles.
Option 3: The server combines all attribute values into a single, concatenated string.
Option 4: Values provided in later profiles or profile-diffs override those from earlier ones.
Explanation: According to the resolution process for merging device capability profiles, when no specific resolution rules are defined in the schema for an attribute, the values from later profiles or profile-diffs are assumed to override the values from earlier ones. This ensures a consistent and predictable outcome in the absence of explicit guidance, allowing the server to deliver content optimized for the client's capabilities as understood from the received (and merged) profiles.
