Add xhtml option to make link tags self-closing

[koenpunt]

Some apps require xhtml tags to be generated (like here webpack-contrib/extract-text-webpack-plugin#160)

[jantimon]

Could you please add a note to the readme and a unit test?

Just thinking - would selfClosingTags be better than just xml ?

[koenpunt]

xhtml could be more than just closing tags. Maybe eventually there are some required attributes on tags in xhtml, which are not necessary for just html

[jantimon]

True but this wouldn't be backwards compatible if we extend xml later on.

[koenpunt]

this wouldn't be backwards compatible

In what way backwards compatible?

extend xml later on

You're planning on xml support? How does that work? And in terms of naming, then the package name would be incorrect too I guess.

[jantimon]

You said you might want to extend the xml feature set for the xml option eventually in future.
This would probably break backwards compatibility for people who set xml to true to get the self closing tags.

[koenpunt]

I didn't mention xml, only xhtml

[jantimon]

Sorry for the confusion I meant xhtml.

[koenpunt]

Setting xhtml to true would mean you expect the output to be XHTML compliant, so as long as that's what is does, there won't be any backward incompatibilities later on.
selfClosingTags would imply there are other reason than being XHTML compliant for self-closing tags to be present.

Not complete sold but sounds okay

[koenpunt]

Cool, could you release a new version of the package? Thanks!
