guiattribute "maxlength" not in validation schema

[musicEnfanthen]

The dsp-tools documentation mentions a maxlength gui-attribute. This attribute is also used in the old Salsah for SimpleText gui-elements.

But in the knora-schema.json that attribute is missing. However, there is another attribute maxsize in the schema.

Should maxsize be corrected to maxlength in the schema, or should we map the maxlength from SALSAH to the new maxsize in the schema?
