WorldViewProjection keyword in DierctX Document

akira32

float4x4 WorldViewProjectionMatrix: WorldViewProjection;
The keyword of WorldViewProjection is used in the FX Composer2?
But I cannot find the description of WorldViewProjection in DirectX SDK's document and FX Composer2's User Guide.
Could somebody know where is the WorldViewProjection and others keyword(after ":") in DirectX SDK Document?

But I still cannot find the definition of WorldViewProjection in "Semantics (DirectX HLSL)".

I want to know the key words,as below:
WorldViewProjection
Wolrd
View Projection
WolrdInver
...... etc

I want to find the complete list of all custom semantics as defined by FxComposer. Could somebody have the list?
