DMN12 — Chapter 11 example in specification does not match file ch11example.xml and ch11example.xml contains errors

The figures in chapter 11 does not match the ch11example.xml file. There are missing requirements, typos and undefined functions.

In order to be able to execute the ch11example.xml file the following erors must be fixed:

• Missing information requirement from "Applicant data" to "Application risk score"
• Missing information requirement from "Applicant data" to "Post-bureau affordability"
• "Bureau call type" decision should have an information requirement from "Pre-bureau risk category" decision and knowledge requirement from
  "Pre-bureau risk category table" should be removed.
• Missing information requirement from "Application risk score" to "Post-bureau risk category"
• Missing information requirement from "Post-bureau risk category" to "Post-bureau affordability"
• Missing information requirement from "Required monthly installment" to "Post-bureau affordability"
• Typo in BKM "Application risk score model": Parameter name should be "Marital Status" (with space)
• Inside "Pre-bureau risk category table" rule 2 and 3 contains wrong expressions for input clause "Application Risk Score". It should be ".." instead of "-" inside ranges
• For the "Bureau call type" decision "Pre-Bureau Risk Category" should be renamed as "Pre-bureau risk category" (as the decision name) on the right.
• For BKM "Affordability calculation" "Disposible Income" should be renamed as "Disposable Income" and for the first context entry "-" minus should be used (not an invalid character)
• In case of "Strategy" decision the input clauses should be corrected as "Eligibility" and "Bureau Call Type" instead of "eligibility" and "bureauCallType"
• For "Post-bureau risk category" decision remove invalid characters from the name of "Application Risk Score"
• The external function "PMT" should be declared. We recommend to add a new business knowledge model "PMT" with a knowledge requirement from that business knowledge model "PMT" to "Installment calculation"

Revision of Chapter 11 example

What has changed?

• All decisions and business knowledge model names were uniformized to lower case
• Decision table "Application risk score model" Age input entries were modified to be complete (ie [18..21], [22..25] were changed to [18..22), [22..26) )
• Everything was recaptured to make sure we had the proper naming in parameters in the decision logic
• XML was generated with DMN 1.2 namespace and the complete DI. There is 6 diagrams corresponding to figure 11.2 to 11.7
• PMT function that is invoked in "Installment calculation decision logic" is now defined in its own file (Chapter 11 Example - Financial.dmn) and this file is imported by Chapter 11 Example. The imported BKM was also added to the proper diagrams.
• A figure of the PMT function was added
