Function valid_content_model 

pub unsafe fn valid_content_model(
    model: *mut _xmlElementContent,
    names: &[*const xmlChar],
) -> ContentModelResult

Validate content (a list of element names) against a content model, taking occurrence indicators into account.

UPSTREAM-PARITY

int xmlValidContentModel(xmlElementContentPtr model, ...)

This implements a simple recursive descent validator for content models. For simple content models (EMPTY, ANY, PCDATA), the check is direct. For sequence/choice models, it recursively validates.

Returns ContentModelResult::Valid if the content matches the model, ContentModelResult::Invalid otherwise.

SAFETY

• model must be a valid pointer to an _xmlElementContent, or NULL.
• names must be a slice of element names (null-terminated xmlChar strings).
