I am using RELAX NG Compact and have run across a case where a sub-element is being used by two independent parent elements. How can I resolve this?
Use case 1
<parent1>
<field usecase_123="test" />
</parent1>
Use case 2
<parent2>
<field usecase_AAA="test" />
</parent2>
Herein lies the conflict:
parent1 = element parent1 { element field { attribute usecase_123 {text} } }
parent2 = element parent2 { element field { attribute usecase_AAA {text} } }
RelaxNG allows an element to have different attributes based on its parent element.
So you can have a RelaxNG grammar like this:
And, valid against that grammar, the following document instance:
