The FME ASPRS las file format 1.4 reader seems to omit withheld points. How do i import all points (including the withheld points ) and then use classification_flag to filter the withheld points in and out? The point cloud splitter doesnt give me classification_flag as an option, and the withheld points dont import via the reader (withheld points verified by lastools), and cant see a parameter to control whether withheld points are imported. Advice welcomed. Thanks in advance.

I was able to create a 1.4 Las file with FME which contains points with classification_flags = 2 and read it back in with FME 2022.2. All points were read by the reader and I was able to split the point-cloud using the PointCloudSplitter. According the the FME docs 2 is the correct value for a withheld point: https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_ReadersWriters/las/quick_facts_las.htm
