Hi Yitzhak, Though Oxygen XML IDE shows the following upon validation: > For simpleType definition '#AnonType_ADDR_TYPE', the enumeration value '' > contradicts with value of 'length' facet.
The warning is not shown as it occurs before the actual validation (i.e, while the schema is compiled). I’ve changed this behavior: With the latest snapshot, schema warnings are considered as well [1]. Best, Christian [1] https://files.basex.org/releases/latest/
