I was looking though the templating documentation for Jinja and noticed that the example does not use the marker keyword in the base template, nor is it used later on in the documentation. However if you look here, marker is used in the example with block.
Why is that? Is marker deprecated? Is one doc more up to date than the other?
Those are documentation for two very different versions of Jinja. http://jinja.pocoo.org/docs/ documents the current version, Jinja2, while http://wsgiarea.pocoo.org/jinja/ documents an old jinja “pre 1.0” version, for historical purposes presumably.
markerwas probably removed in Jinja2 because it is equivalent to an emptyblocktag.
