var predicate = require('commonform-predicate')The exported functions can be used to find the type of a content array element in a known-valid form, to avoid doing all that's necessary to ensure validity.
If you a know a form object is valid, and need to pick out specific content elements, use commonform-predicate, not commonform-validate.
var assert = require('assert')
var invalid = { invalid: 'object' }
var validForm = { content: ['Valid text'] }
assert(predicate.definition({ definition: 'Term' }))
assert(!predicate.definition(invalid))
assert(predicate.use({ use: 'Term' }))
assert(!predicate.use({ term: 'Term' }))
assert(predicate.reference({ reference: 'Term' }))
assert(!predicate.reference(invalid))
assert(predicate.blank({ blank: 'Value' }))
assert(!predicate.blank(invalid))
assert(predicate.link({ link: 'https://example.com' }))
assert(predicate.link({ link: 'http://example.com' }))
assert(!predicate.link(invalid))
assert(predicate.child({ heading: 'Summary', form: validForm }))
assert(!predicate.child(invalid))
