Is there any way to achieve the same effect of 'relevant' MIP with XML Schema?

Dear All,

XForms supports two ways of performing validation:

1. With Model Item Properties (MIPs) in the model, called constraint and
type.
2. With an XML Schema. XML Schema is a W3C standard to specify
constraints on XML documents, including constraints on the structure of
the document or on the data types contained.

<xforms:bind nodeset="verification-code" relevant="../type = 'visa' or
../type = 'mastercard'"/>

Is there any way to achieve the same effect with XML Schema?

I means "conditional structure" quoted from
http://xsd.stylusstudio.com/2001Sep/post04015.htm.

Regards,
Sardine Kao.

Administrator

Sardine,

In XForms, validation strictly impacts the "valid" and "type"
properties, but not relevance.

So the answer is no, at least not out of the box.

You could probably pre-process a schema (e.g. with XSLT) in order to
produce relevance binds though.
