5.2.1.2 enctype="..." attribute

If you include any file input fields then the open tag will automatically supply an enctype="multipart/form-data" attribute.

>>> import albatross
>>> from fakeapp import ctx
>>> albatross.Template(ctx, '<magic>', '''
... <al-form whitespace>
...  <al-input type="text" name="name" whitespace>
...  <al-input type="file" name="data" whitespace>
... </al-form whitespace>
... ''').to_html(ctx)
>>> ctx.flush_content()
