Not sure to follow, anyway, WRT to
`<text>bkm_001({name: "foo"})</text>`
1. our engine detect that `bkm_001` requires a `tNameAndAge`
2. it tries to parse `{name: "foo"}` as `tNameAndAge`, but due to missing
property (`age`) validation fails, and translate to `null`
3. so, the invocation become `bkm_001(null)`
4. and bkm_001 in this case return `false`
As "wrong parameter", as per bkm definition
```xml
<businessKnowledgeModel name="bkm_001" id="_bkm_001">
<variable name="bkm_001"/>
<encapsulatedLogic>
<formalParameter name="nameAndAge" typeRef="tNameAndAge"/>
<literalExpression>
<text>nameAndAge != null</text>
</literalExpression>
</encapsulatedLogic>
</businessKnowledgeModel>
```
`null` is a perfectly valid parameter for it
AFAIK, the engine/spec has always been extremely permissive with `null`,
i.e. whenever an expression can't be parsed to object, it is simply translated
to `null` without any error thrown, by itself.
So, in this case, it is not clear to me how we could implement that.
