The DTD zip file that is in SAP Marketplace does not contain the correct DTD's.
There are also DTDs shared in Partner Portal from 30th September but alas they are not correct.
As stated by original post, they do not contain the DTD codes but some entry of file logs.
This is the error you get for example in the GM DTD file from Marketplace.
It would be great if we as partner implementors could get the correct versions from SAP.
What is more alarming is that I am assuming since many consultants globally have not all voiced this issue, then it could only mean that many consultants work without DTD and validation.......not best practice.....
