Cannot view the member datatype of a simple non-nested compound datatype

1. File: ftp://ftp.hdfgroup.uiuc.edu/pub/outgoing/HDFCompass/kent-files/hdf5-handler-fake/d_compound.h5
1. Testing version: Windows version of the release candidate from S3
2. Issues about viewing the data:
1) I can view the data of the dataset correctly. However, there is no way for me to check the datatype of the member of the compound datatype dataset. All I see is Type Compound(4 fields). I like to see the first field type is i4 etc.
2) This file also has a compound datatype attribute called "value" with the exact the same values as the dataset. I can check the member Type of this compound datatype attribute. This is good in general. However, for a member HDF5 variable string, the Type is represented as ( "Location", 'O'), I don't understand what this O means. It should be "str" in my opinion.

Reproduce the report with ftp://ftp.hdfgroup.uiuc.edu/pub/outgoing/HDFCompass/kent-files/hdf5-handler-fake/d_compound.h5 using the Windows release candidate mentioned in the issue. Compare the dataset's compound-member display with the compound attribute named "value", including the variable-string type; done means the dataset members are inspectable and the string type is understandable.
