LTLOG11 — use of IDL type string for data that's logged is not cross-language compati

Discussion:
The data that can be logged with the Lightweight Log service is an encoding of arbitrary binary data. The type used in the ProducerLogRecord for this data is "string" in both the PIM and the PSM. This is inappropriate, since strings are not considered to be arbitrary encodings. They are associated with particular (and different) character encodings in different technologies. This can be seen even within the CORBA PSM, where the Java language mapping transforms a string to sixteen-bit characters internally.

Proposed Resolution:
Change the type of the logData field in the ProducerLogRecord to OctetSeq
