+ISSUE:       https://github.com/FirebirdSQL/firebird/issues/7537
+TITLE:       Add ability to query current value of parallel workers for an attachment
+NOTES:
+    [03.04.2023] pzotov
+    ::: NB :::
+    This is INITIAL version of test.
+    It checks only *ability* to query values from mon$attachments and rdb$get_context.
+    It does NOT check tag fb_info_parallel_workers because this is not yet implemented
+    (BTW, 'isc_dpb_parallel_workers' also not yet avaliable in the firebird-driver).
+    ==============
+    doc/README.parallel_features.txt:
+    Default value is 1 and means no use of additional parallel workers. Value in
+    DPB have higher priority than setting in firebird.conf.
+    ...
+    ParallelWorkers - set default number of parallel workers that used by user attachments. 
+    Could be overriden by attachment using tag isc_dpb_parallel_workers in DPB.
+    ==============
+
+    Checked on intermediate snapshot 5.0.0.1001.
