A coxph object is the result of fitting a proportional hazards regression model, using the "coxph" function from the package survival. Although the survival package supports special terms "cluster", "tt" and "strata", only the special term "strata" is supported by the pmml package. Note that special term "strata" cannot be a multiplicative variable and only numeric risk regression is supported.
