<p class="MsoNormal"><span lang="EN-US">I am trying to create a layer in an existing feature dataset in an existing File Geodatabase (FileGDB, not Open) using python and GDAL/OGR from OSGeo.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">The following is my code attempt:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Yes I didn’t provide a spatial reference, but if None is invalid I might as well pick one used by an existing layer inside the feature dataset:<o:p></o:p></span></p>
