How to check the text syntax of a Simulink model

Question

I want to check if the mdl file of a Simulink model is syntactically correct or not. I don't want to load the model because I am only interested in the syntax errors, not the semantic issues (i.e. unconnected lines, etc.) Consider the example:

Model {
Name toy
System {
Name toy
Block {
BlockType DiscreteTransferFcn
Name "cfblk1"
}
Block {
BlockType Display
Name "cfblk2"
}
Line {
SrcBlock "cfblk1"
SrcPort 1
DstBlock "xyz"
DstPort 1
}

}
}

Here, the model is syntactically correct, but semantically the Line is not correct. Because there is no existing Block titled xyz. If I load the model then it will raise warnings:

Warning: sample.mdl, line 18: Attempt to set DstPort with invalid Destination
> In load_system (line 21)

Is there any way to validate the syntax of mdl files without loading them into memory?
