The note makes an absolute compatibility claim ("assemblies ... cannot be loaded") without explaining the limitation. Consider rephrasing to the supported statement (for example, that assemblies produced by the .NET Framework xsltc.exe target .NET Framework and might fail to load on .NET Core/.NET 5+ due to missing dependencies), so the guidance stays accurate and actionable.

Format xsltc.exe as code (xsltc.exe) and consider splitting this note into shorter sentences (it currently repeats "on .NET Core or .NET 5 or later" and is hard to scan).

Richard Lander was recently pointing out to me that "modern .NET" isn't a thing. It's .NET or .NET Framework.

The XSLT compiler (xsltc.exe) compiles XSLT style sheets and generates an assembly. The assembly can be passed directly into the <xref:System.Xml.Xsl.XslCompiledTransform.Load(System.Type)?displayProperty=nameWithType> method.
