ACE notes "serious" issue for incorrect lang attribute of html files in generated EPUB3

Expected Behavior

When running the dtbook-to-epub3 script on DAISY books, the EPUB3 result should have HTML files with a correct "lang" attribute for the element.

Actual Behavior

Running ACE against the EPUB3 output generates a report pointing out the missing property.
{ "@type": "earl:assertion", "earl:result": { "earl:outcome": "fail", "dct:description": "Value of lang attribute not included in the list of valid languages", "earl:pointer": { "cfi": [ "/" ], "css": [ "html" ] }, "html": "<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"eng\">" }, "earl:assertedBy": "aXe", "earl:mode": "automatic", "earl:test": { "earl:impact": "serious", "dct:title": "html-lang-valid", "dct:description": "Ensures the lang attribute of the <html> element has a valid value", "help": { "url": "http://kb.daisy.org/publishing/docs/html/lang.html", "dct:title": "Language", "dct:description": "<html> element must have a valid value for the lang attribute" }, "rulesetTags": [ "cat.language", "wcag2a", "wcag311", "ACT", "TTv5", "TT11.a" ] } }

Steps to Reproduce

I'm running the Pipeline2 as a web service in a Docker container, as described in #674.

The script is run via curl:
$ curl -v -X POST --form job-data='@Charlotte_s_Web.zip' --form job-request='@pipelineRequest_Charlotte.xml' http://localhost:8181/ws/jobs

The job request file looks like this:
<jobRequest xmlns='http://www.daisy.org/ns/pipeline/data'> <script href='http://localhost:8181/ws/scripts/dtbook-to-epub3'/> <input name='source'> <item value='Charlotte_s_Web.xml'/> </input> <option name='assert-valid'>false</option> </jobRequest>

The ACE report was then generated with this:
$ ace --subdir --silent --outdir ace_charlotte Charlotte_s_Web.epub

Details

The input DAISY package can be provided by an alternate channel.

The guidance from the W3C suggests that we might want both "lang=" and "xml:lang=" as attributes.

Environment

  • Operating system: Linux 64-bit
  • DAISY Pipeline 2 version: 1.14.14
  • Interface: web service API
  • ACE: 1.3.1
