Re: [xmljs-users] Namespace validation question

[Ilya B. <il...@dr...>]

Dmitry,

Thanks for the quick reply.  Perhaps I am not reading the spec correctly. 

To me,

"It MAY, but need not, be declared..."

Means that not declaring the namespace explicitly should be OK.
And if I am wrong about this, what would be the correct way to re-write
the following tag so that the xml:lang attribute namespace validates?

<text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" xml:lang="en"/>

Thanks,
Ilya
