Rendering is broken with haml 5.0

[abrisse]

rdf/rdfxml does not work anymore when using haml 5. It produces invalid XML.

script.rb

require 'rdf/rdfxml'

RDF::NTriples::Reader.open('file.nt') do |reader|
  puts reader.dump(:rdfxml)
end

file.nt

Please verify that this is fixed on the develop branch, and I'll release it.

[abrisse]

Awesome. That fixes the closing tag problem, but the indentation is still broken.

[abrisse]

It seems that haml 5 removes the ugly option that allowed to indent the content. :(

Otherwise the closing tags work on the master branch when running:

reader.dump(:rdfxml, haml_options: { format: :xhtml})

Is that OK if I create a PR for the master branch that always set that option?

[abrisse]

I mean a PR on the rdf-rdfa gem on the RDF::RDFa::Writer#hamlify function that instiate the HAML engine

[gkellogg]

Released fix using closing tags in 2.1.0.
