Description

Some of the languages have

@XmlAttribute(name = "resultType")
private String resultTypeName;
@XmlTransient
private Class<?> resultType;
@XmlAttribute
@Metadata(label = "advanced")
private String headerName;
@Metadata(label = "advanced")
private String propertyName;

We need to have this for more languages (all but not)

• header
• exchange property

So we could maybe have a class that extends ExpressionDefinition and then have the above options which other languages can extend to make it reuable and consistent.

This then also requires to update

• reifier
• builder
