custom fields / xml attribute

Absolutely love this plugin, does 99% of what I need a super lightweight.

I am having one problem however with XML attributes.

For example, I’m trying to Map a custom field of ‘enclosure’, but I need the URL attribute and your plugin sadly does not seem to offer a way to target that? Can you suggest anything?

Your plugin certainly sees the attribute, but adding enclosure as a custom field does not display anything…

/enclosure:

ATTRIBUTES:
