/*!
Format XML Templating
=====================

Minimal compiletime templating for XML in Rust!

The [`format_xml!` macro](macro.format_xml.html) accepts an XML-like syntax and transforms it into a `format_args!` invocation.
We say _XML-like_ because due to limitations of the macro system some concessions had to be made, see the examples below.

See the [`template!` macro](macro.template.html) to get started with regular formatting.
