# Option default_attributes
#
# A hash of default attributes for tags (`{tag => {attribute => default_value}}`).
# Attributes of each tag will reverse merged with his default attributes, so you
# don't have to write over and over that script tag has attribute `type` with value
# `text/javascript`. For example, `%script` compiles to `<script type="text/javascript"></script>`.
# Defaults to `{script: {type: "text/javascript"}, form: {method: "POST"}}`
