<elevationGrid> not supported in OpenDRIVE Conversion with NetConvert

[0graph]

NetConvert does not support the <elevationGrid> tag in OpenDRIVE 1.8.1

The reason for this is that it expects all <elevation> tags to have s,a,b,c,d elements but the <elevation> tag for <elevationGrid> has: center,left,right

Error:

Error: Attribute 's' is missing in definition of elevation '100665'.

Attached is a sample opendrive (renamed as .xml so github would support upload) I generated automatically with real world elevation that has this issue.

As mentioned in issue #16283 , the OpenDrive implementation isn't complete and probably lagging behind the latest standard. It is updated depending on user needs. If the elevation tag depends on the context in OpenDrive 1.8.1 this has not been integrated yet.

support for loading the data is not planned for the moment, but reading files with such data is now working (rather than giving an error).
As a workardound (instead of upgrading to the dev version), it's also possible to convert the network with option --ignore-errors.
