 libdatrwxx: MiniSEED consistency checks
 ---------------------------------------
 
-@yt6233 reports problems with content consistency of LED-written data. The
-file uses less frames than announced in the Data Extension Blockette [1001].
-The library should provide better means (through format modifiers) to users to
-control the effect of consistency checks.
-
 As a reminder:
-- rework exception and warning messages to be comprehensible to users
-  - mention check ID in message from consistency check
-  - give proper reference to format modifiers which might help to overcome a
-    problem
-  - let exepction objects store a string value in order to be able to compile
-    more complicated strings
-  - allow compilation of message strings in macros
-  - give a meaningful introduction to exception reports
 - check application of time correction before finishing this issue
   time correction is not part of this issue, however Chad Trabant has made a
   respective note in libmseed - I like to make sure that libdatrwxx does it
