What does this mean “xmlns:xliff”? XML

Question

What does this mean?

Answer 1

XLIFF is the OASIS XML Localisation Interchange File Format.

xmlns:xliff is an XML attribute name. The :xliff indicates we are using the xliff namespace.

urn:oasis:names:tc:xliff:document:1.2 identifies the schema location; the choice of format is at the discretion of Oasis, I'd assume it has meaning.
