HLSL VFXFIXED_RAND isn't working in custom HLSL while mentionned in the doc

Steps to reproduce:

1. import the procided Package

2. Drag and Drop the VFXG_RandomHLSL.vfx in a scene

3. Open the VFXG_RandomHLSL.vfx

4. Notice that the Graph isn't compiling and spill errors:

Actual results: 

Shader error in '[VFXG_RandomHLSL] [Simple Burst] Initialize Particles': 'asuint': no matching 1 parameter intrinsic function; Possible intrinsic functions are: asuint(double, out uint x, out uint y) asuint(float|half|int|uint) at kernel CSMain at VFXG_RandomHLSL.vfx(192) (on d3d11)

 

Shader error in '[VFXG_RandomHLSL] [Simple Burst] Initialize Particles': undeclared identifier 'systemSeed' at kernel CSMain at VFXG_RandomHLSL.vfx(192) (on d3d11)

 

Shader error in '[VFXG_RandomHLSL] [Simple Burst] Initialize Particles': undeclared identifier 'VFXFIXED_RAND' at kernel CSMain at VFXG_RandomHLSL.vfx(192) (on d3d11)

 

Expected results: As stated by the doc, user should be able to generate Fixed random value easily thanks to this function:
https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@17.0/manual/Block-CustomHLSL.html

Reproducible with versions: 

Not reproducible with versions: 

Can’t test with versions: 

Tested on (OS): 

Notes:

• The Documentation also seems a bit imprecise:

This seems wrong. The correct doc could be:
Generate a random scalar value for each VFX Graph system.
