Additional Context

Summary: System.Xml.Tests.XslCompiledTransformApi.Errata4.TestXslTransform fails on tvos-arm64 with System.UnauthorizedAccessException when attempting to access xmlResolver_document_function_absolute_uri.xsl inside the tvOS app bundle. The tvOS sandbox restricts file access in the app bundle directory.

Failed in (2+):

• runtime-extra-platforms 1414719 (2026-05-10)
• runtime-extra-platforms 1414320 (2026-05-09)

Failed tests:

runtime-extra-platforms (tvos-arm64 Release AllSubsets_CoreCLR)
- osx.15.amd64.appletv.open
  - System.Xml.Tests.XslCompiledTransformApi.Errata4.TestXslTransform

Error Message:

[FAIL] System.Xml.Tests.XslCompiledTransformApi.Errata4.TestXslTransform
System.TypeInitializationException : The type initializer for 'System.Xml.Tests.XslCompiledTransformApi.Errata4' threw an exception.
---- System.UnauthorizedAccessException : Access to the path '...xmlResolver_document_function_absolute_uri.xsl' is denied.

Impact on platforms:

• runtime-extra-platforms + tvos-arm64 + osx.15.amd64.appletv.open

Recommended action: The tvOS sandbox prevents write access to certain paths within the app bundle. The test or its test data setup may need to use a writable directory (e.g., Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)), or the test should be annotated with [ActiveIssue] for tvOS until the root cause is fixed.
