Failure in building StatDataML for Octave 2.1.57

After posting the message below in help-octave, I realized that
octave-maintainers would be a more appropriate forum.  Sorry for the

Hi,

I am trying to build the StatDataML package (
http://cran.r-project.org/src/contrib/StatDataML_1.0-6.tar.gz) for Debian
using Octave 2.1.57.  Compilation fails with the following error message:

mkoctfile -I/usr/include/libxml2 -lxml2  readsdml.cc
readsdml.cc: In function `octave_value* GetStructureData(int*, char**, 
   xmlNode*)':
readsdml.cc:987: error: no match for 'operator[]' in 'A[*(names++)]'
readsdml.cc: In function `octave_value* GetDescription(xmlNode*)':
readsdml.cc:1093: error: no match for 'operator[]' in 'S["properties"]'
readsdml.cc:1095: error: no match for 'operator[]' in 'S[Cur->_xmlNode::name]'
make[2]: *** [readsdml.oct] Error 1

Compilation was okay with Octave 2.1.50 and if I replace the lines like:

    Octave_map A;
    char** names;
    // ...      
    A[*names++] = *GetDataset(Cur);

by:

    A.assign (*names++, *GetDataset(Cur));
      
then compilation with 2.1.57 succeeds.  I am wondering why the [] operator
for the Octave_map class is not supported anymore.  Is the "assign" method
above backward compatible with older versions of Octave?
