- Removed lxml extra, as we do no longer depend on it. [malthe]
- Make sure the path expression is a simple string, not
unicode. [malthe]
- Detect path prefix properly for ViewPageTemplateFile usage in
doctests. [sidnei]
- The ``template`` symbol is already set by the template base
class. [malthe]
- Set Content-Type header, for backwards compatibility with
zope.app.pagetemplate. [sidnei]
