+# This script demonstrates how to read connector-specific connection attributes
+# (Oracle service, Snowflake schema, Teradata query-band, initial SQL, etc.) that
+# the Tableau REST API's `<connection>` element does NOT expose.
+#
+# The REST API's `.populate_connections()` surface only carries generic fields
+# (id, type, server_address, server_port, username, embed_password, auth_type).
+# The full set of connector-specific attributes lives inside the workbook or
+# datasource file itself. This sample downloads the file via TSC, then parses it
+# with the community `tableaudocumentapi` library to reach the extra attributes.
+#
+# Requires:
+#   pip install tableauserverclient tableaudocumentapi
+#
+# Related GitHub issues:
+#   - server-client-python#1807 (Oracle service on ConnectionItem)
+#   - server-client-python#1571 (database_name on ConnectionItem)
+#   - server-client-python#160  (queryband, initial_sql)
+#   - server-client-python#353  (SQL Server database + schema + table)
+#
+# To run the script, you must have installed Python 3.10 or later.
