The lang attribute specifies the primary language used in contents and attributes containing text content of particular elements.
There is also an {{SVGAttr("xml:lang")}} attribute (with namespace). If both of them are defined, the one with namespace is used and the one without is ignored.
In SVG 1.1 there was a lang attribute defined with a different meaning and only applying to <glyph> elements. That attribute specified a list of {{glossary("BCP 47 language tag", "BCP 47 language tags")}}. The glyph was meant to be used if the xml:lang attribute exactly matched one of the languages given in the value of this parameter, or if the xml:lang attribute exactly equaled a prefix of one of the languages given in the value of this parameter such that the first tag character following the prefix was "-".
You can use this attribute with any SVG element.
<svg viewBox="0 0 200 100" xmlns="http://www.w3.org/2000/svg">
<text lang="en-US">This is some English text</text>
</svg>
<language-tag>
: This value specifies the language used for the element as a valid {{glossary("BCP 47 language tag")}}.
The most common syntax is a value formed by a lowercase two-character part for the language and an uppercase two-character part for the region or country, separated by a minus sign, e.g., en-US for US English or de-AT for Austrian German.
