Subject: Re: [xsl] XML schema: require a descendant? From: "Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Sat, 8 Jul 2017 17:40:14 -0000 |
Hey Chuck, Another route to XPath-based validation -- wherein you could implement a rule for your entry that at least one 'sense' child has some-child-or-other -- would be embedding Schematron in your schema -- or maintaining an extra-schema constraint layer (in the form of a Schematron) -- and then doing it there. You can embed Schematron into RNG or XSD given support from tools (such as oXygen). But you might start with an external Schematron - or you could go full-bore TEI and do it in an ODD ...
