Re: No error message with this erroneous DFDL property ... dfdl:engthUnits="bytes"

[Steve Lawrence <sl...@apache.org>]

We actually just pushed a change to the master branch last week to
validate the short-form and attribute-form properties. So the next
Daffodil release will throw an error in this case. I think we've all
wasted a bunch of time due to typos like this. It'll be nice to have the
feature in.

Related, we also just pushed a change that warns if there are DFDL
properties that were not used. For example, if you had

  <xs:element name="foo"
    dfdl:lengthPattern="..."
    dfdl:lengthKind="explicit" ... />

In this case, the dfdl:lengthPattern property will be ignored, and will
now result in a warning. This kind of issue is also a common cause of
wasted time and headaches.
