Bug in meta-tag?

Adding a meta-tag to my XPage using the xp:metaData-tag inside xp:this.resources.

One this is that I am forced to add a “name”-attribute.

But why is the -tag on my HTML-page generated with an attribute “httpequiv”? According to the standard, the attribute is named “http-equiv”.

See : The global structure of an HTML document

How can I add a (correct and working) meta-tag to my XPage?
