-----------------------------------------
Summary: Ensure "lang" attribute is set in <html> tags
Key: NIFI-9816
URL: https://issues.apache.org/jira/browse/NIFI-9816
Project: Apache NiFi
Issue Type: Bug
Components: Core UI, NiFi Registry
Affects Versions: 1.15.3
Reporter: Jonathan Conti-Vock
Accessibility standards require every <html> tag to have a "lang" attribute
where the value represents the primary language of the document. From the [WCAG
2.1 requirement's
description|[https://www.w3.org/WAI/WCAG21/Techniques/html/H57|https://www.w3.org/WAI/WCAG21/Techniques/html/H57]:]],
identifying the language of the document is important for a number of reasons:
* It allows braille translation software to substitute control codes for
accented characters, and insert control codes necessary to prevent erroneous
creation of Grade 2 braille contractions.
* Speech synthesizers that support multiple languages will be able to orient
and adapt to the pronunciation and syntax that are specific to the language of
the page, speaking the text in the appropriate accent with proper pronunciation.
* Marking the language can benefit future developments in technology, for
example users who are unable to translate between languages themselves will be
able to use machines to translate unfamiliar languages.
* Marking the language can also assist user agents in providing definitions
using a dictionary.
While reviewing the backlog for existing tickets related to localization, I
found there's already been some significant (though stale) work done to
implement localization/multilingualization (NIFI-4785). Given that work, I
would suggest compatible JSTL changes be made to the existing JSPs and
otherwise hardcode lang="en" in existing HTML pages until further localization
improvements are made.
