You can use the PMML converter to validate your PMML file against the specification for versions 2.1, 3.0, 3.1, and 3.2. If validation is not successful, the converter will give you a file back with explanations for why the validation failed (click on the "details" hyper-link).

So, before actual conversion takes place, the validation phase needs to be successful, i.e. your file needs to conform to the PMML specification as published by the DMG (for any of the older PMML versions listed above).

The PMML converter currently converts the following model elements to PMML 3.2:

• Neural Networks
• Decision Trees
• Support Vector Machines
• General Regression
• Regression
• Clustering Models
• Association Rules
• Naïve Bayes Classifiers

It will also convert pre- and post-processing PMML elements.
