can NXlog/value be used to record strings or boolean readouts ? #1432

It is convenient to record string-like status of the hardware or bool-like hardware flags. Ideal for those purpose would be NXlog/value. However, in the documentation NXlog/value is of NX_NUMBER type. It would be good to extend it by NX_BOOLEAN and NX_CHAR. Especially that in the documention it is written that and NeXus field which changes during the experiment can be replaced as an NXlog group.

The intent of NXlog (as it is described) is to log numerical data. Expanding to non-numerical types could have consequences for software which expects only numbers.
