[Zope-dev] Where to put custom schemas for z3c.form that depend on specific libraries?

Hi, I need to create a specific schema for international bank account numbers (IBAN). I'd like to contribute this widget (maybe someone has use for it). However, this schema needs a specific library for validation, therefore I wonder where to put it? If I put it in z3c.schema (e.g. z3c.schema.iban / z3c.schema.payment), the library dependency will be problematic, I assume. Maybe I should create an own package for it? But with what name? What do you think? Best Regards, Hermann -- hermann@qwer.tk GPG key ID: 299893C7 (on keyservers) FP: 0124 2584 8809 EF2A DBF9 4902 64B4 D16B 2998 93C7
