Invalid modification of attribute's simpleType

… detected during schema update

Hi all,
I would want to modify the type of an attribute (xs:string → xs:integer) but Tamino does not allow me (but I have verified that the attribute contains numerical values only). Could you help me to understand why?
Thanks in advance!


Hi Pam,
Tamino wants to be 110% sure that all existing data are valid according to the revised schema :wink:

What you should do is to call the “Define Schema with Instance Check” in the database menu in the schema editor.
But beware this will validate every single document in the DB against the new schema !!! - might take some time with a 10Mio DB…


Hi Finn,
you are right: finally the schema has been updated!
Thank you very much for your precious help!
