Hi,
I have a problem about exporting the aviation geodatabase to AIXM 5.1 to use with another program.
I've already create a runway and related features as shown below

Problem 1:
I import exported AIXM file from ArcGIS to another program it show error as below

When I compare AIXM file with another program I found this

The "xsi:nil = "true" is the different and when I deleted this text, this error disappear.
How can I prevent this text appear when I export AIXM or I have to delete it manually?
Is there any field that I must input the data to prevent this text appear?
Problem 2: Missing aixm:usedRunway line in exported AIXM
I've already link the all features' relationship start with ADHPSurfacePoint > ADHPThreshold > ADHPSurfaceLine > ADHP.
But when I export geodatabase to AIXM 5.1 the problem I've found is this error when I import this AIXM to another program. The "aixm:usedRunway" line in the AIXM file are missing.


And I've check the table of ADHPSurfacePoint. The ADHPSurfaceArea_Id has already linked.

How can I fix this error when I export AIXM file?
