I know someone recently was ranting about the casing of attribute names in OPML htmlUrl vs htmlurl, but I can’t find the post now. Anyway Chris Pirillo ran into a problem trying to import his OPML into blogToaster, so it will now happily accept either htmlUrl or htmlurl. Enjoy!
Is one usage or another the ‘defacto’ standard?
Of course, the answer is the age old be liberal in what you accept and conservative in what you send. Send only the correct usage, but be prepared to accept any variation on the standard.
