Adds 8 E2E acceptance tests covering published element extension methods: invariant/variant rendering, explicit culture arguments, composition (IsDocumentType recursive + IsComposedOf), equality (IsEqual/IsNotEqual), and language fallback. Two new DocumentTypeApiHelper factory methods and four new TemplateApiHelper template builders support the tests.

Suggestions

• tests/Umbraco.Tests.AcceptanceTest/lib/helpers/DocumentTypeApiHelper.ts:626: The new createElementTypeWithComposition is nearly identical to the existing createElementTypeWithAComposition (line 596). Key differences: new one adds .withAllowedInLibrary(true) but omits .withIcon("icon-plugin"); old one has the icon but not allowedInLibrary. Every other element-type helper in this file that sets withIsElement(true) either adds an icon, allowedInLibrary, or both — omitting the icon here is inconsistent. Consider adding .withIcon("icon-plugin") to the new method, or consolidating the two helpers by adding withAllowedInLibrary(true) to the existing one. Fix this →

• tests/Umbraco.Tests.AcceptanceTest/tests/DefaultConfig/RenderingContent/PublishedElementExtensions.spec.ts:73: Test 1 (can render published element extension methods on an invariant element) asserts HasCultureEn: False but doesn't assert HasCultureDa: False, even though the template emits both lines. On an invariant element with no Danish language configured, both should be False — asserting both would complete the invariant-element contract. Fix this →
