Thanks for taking the time to check this. Given the care with which
gdal is maintained and it's foundational position in the GIS world,
I would have been surprised if it was not conformant to the
standard.<br>
<br>
I used the same utility you found and got the same results, which is
what triggered the exchange with the developer of the PHP shapefile
library. I will pass on this information.<br>

I've also inspected the provided ESRI Shapefile layers and it
seems to me they are perfectly compliant to the Shapefile
technical description
<a class="moz-txt-link-freetext" href="https://downloads.esri.com/support/whitepapers/mo_/shapefile.pdf">https://downloads.esri.com/support/whitepapers/mo_/shapefile.pdf</a>
for PointZ PolyLineZ Shapefile types and are correctly displayed
even using ESRI ArcMap 9.3.1.
<br>
<br>
The ArcMap tool to validate the geometries and the ShapeChecker
utility, recommanded by ESRI, didn't find any error in such
layers.

David, what online utility have you used? I've uploaded
driveway_points[.shp|.shx|.dbf] to
<a class="moz-txt-link-freetext" href="https://www.litchiutilities.com/shapefileToCsv.php">https://www.litchiutilities.com/shapefileToCsv.php</a> and while it
generates 2 warning messages* it also nevertheless creates the
requested CSV file.
<br>
<br>
Regards.
