I couldn't get my website to validate in W3C markup validation.
Here is an example of one of the validation errors.
Error: Attribute xmlns:content not allowed here.
I have done some research and some articles recommend us to change the:xmlns:name="http://url" syntax into the prefix="name:http://url"
However I am having multiple xmlns attribute.
Not sure how to write the prefix in this case.
Original:
`<html lang="en" dir="ltr" xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:dc="http://purl.org/dc/terms/" xmlns:foaf="http://xmlns.com/foaf/0.1/" xmlns:og="http://ogp.me/ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:sioc="http://rdfs.org/sioc/ns#" xmlns:sioct="http://rdfs.org/sioc/types#" xmlns:skos="http://www.w3.org/2004/02/skos/core#" xmlns:xsd="http://www.w3.org/2001/XMLSchema#">`Is it separate by a space between each attribute?
<html lang="en" dir="ltr" prefix="content:http://purl.org/rss/1.0/modules/content/ dc:http://purl.org/dc/terms/ foaf:http://xmlns.com/foaf/0.1/">
or we should separate by \n new line?
I have checked in w3.org website and it looks like they separate the attribute in new line.
Am I right?
