Robert,
In the first paragraph of section 1.4 you that DFDL is used to describe
XML files. I thought this was not the aim of DFDL as standard XML Schema
can be used to describe XML files.
In the third paragraph of section 1.6
you say that 2 DFDL Schemas could be used, one to raad the data and trhe
second to write it. If selectors are used this would be possible using
a single DFDL Schema.
In section 2.3.1.1 you discuss specifiying
multiple inputs. As this has not been discussed in any detail before I
think a new entry is required on the issues list.
In the parsing example in section 6
you say in paragraph 3 that layer 2 reads bytes from layer 1 until one
string has been read. How would you know that you have a one string for
layer 2? In reality I don't think layer 2 is necessary. I think what you
describe as layer 3 would read bytes from layer 1 as characters until a
comma was found. This would then indicate that this was the end of the
string for layer 3.

[dfdl-wg] New draft of DFDL
primer
Greetings,
I have been plugging away on the primer document. There are still
major holes which await development of the specification and/or
input from others.
This draft include considerable revisions based on what I learned
from you all in Boston.
I attach my current draft here. It is also available at:
