This plugin works well with Tim Pope's fugitive plugin, but you can also install manually.

1. Check out the repository with Git, or use the "Download Source" link on the Github homepage.

2. Copy the files into ~/.vim/. You should end up with a structure like:

   • ~/.vim

     • compiler/

       • xmllint_sld.vim

     • xsd/

       • filter/

       • gml/

       • sld/

       • xlink/

In vim, open an SLD file as normal. Use :compiler xmllint_sld to activate the compiler plugin, then :make % to get a validation report in vim's compiler error list.
