xs:date index problem

Hi,

Why cant i make my field of type xs:date in tamino schema editor be an index field? I always get this error message when defining this schema:

An error occured while processing a schema document; (mp-valid-index.1) invalid index

Any idea what i missed? Or is there any prerequisite to be able to define a field of type xs:date with an index.

As far as I know indeces for xs:date fields are not supported in the current version. This is planned for the next version (4).

But if you store date as yyyy-mm-dd (like recommended by XML Schema) in a string field then there will be no problem to search intervals and use sort clause. Plus you will be able to load the same documents in new Tamino with full index support when it becomes available.
