- Add dual-sourced $ac:langs param in imports/default.xsl: navigator.languages primary subtags client-side (SaxonJS), Accept-Language server-side (SAXON), plus $ac:lang for collation/formatting - Per-vocab ac:label/ac:description templates negotiate over the ordered preference list; fallback is untagged-else-first — always a single literal - Drop per-file $ldt:lang params; $ldt:lang remains the negotiated Content-Language carrier, declared in imports/default.xsl - Add AC.langs term; XSLTWriterBase passes the request's q-sorted Accept-Language primary subtags as the ac:langs stylesheet param Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
SaxonJS 3 converts the JS array to a sequence of xs:untypedAtomic, so the JS-style length/index read threw XPTY0004 and $ac:langs evaluated empty — suppressing every language-tagged property value client-side. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
No SaxonJS/browser knowledge in Web-Client — the ixsl-sourced declaration moves to LinkedDataHub's client.xsl, which overrides this default by import precedence. Drops the use-when pair and the ixsl namespace. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ranch Web-Client is strictly SSR. The stub now just terminates if invoked as XSLT: server-side the registered UUID extension function overrides it, client-side stylesheets override it by import precedence. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The writer no longer passes the negotiated Content-Language as a stylesheet param — Accept-Language (ac:langs) is the single input, and $ac:lang = ($ac:langs[1], 'en')[1] is derived, not passed. <html lang>, format-date/format-dateTime, sort collations and the TableDataCell language filters all use $ac:lang; the remaining dual use-when sort pairs are collapsed. $ldt:lang survives only in commented-out templates.

Summary
$ac:langs— an ordered language preference list (negotiation input), distinct from$ldt:langwhich carries the negotiatedContent-Language(output). Declared inimports/default.xslwith a product-agnostic default derived from$ldt:lang; consumers override it:XSLTWriterBasepasses the request's q-sortedAccept-Languageprimary subtags (newAC.langsterm), and client-side stylesheets (e.g. LinkedDataHub'sclient.xsl) override it with the browser'snavigator.languages.ac:label/ac:descriptiontemplate pairs (rdfs,dc,dct,skos,sioc,foaf,doap,schema) from single-language$ldt:langfiltering to ordered negotiation: first preferred language with a match wins; fallback is untagged-else-first — always exactly one literal. Fixes labels disappearing (or all languages being emitted by downstream overrides) when the client's top preference has no match.@ltliteral wins for anlt-preferring user even thoughContent-Languagenegotiates toen/es.ixsl/browser references remain. Theac:uuid()stub drops its SaxonJS branch (client-side implementations override by import precedence; server-side the registeredUUIDextension function wins as before).Test plan
Accept-Language: es,lt;q=0.9,en-US;q=0.8,en;q=0.7,lt,en-US;q=0.9,en;q=0.8, anden-US,en;q=0.9: UI chrome and data labels each resolve to the first available preferred language, single literal, SSR/CSR consistent.🤖 Generated with Claude Code
