Right but still need dfdl:inputValueCalc
to get the @ into the infoset, as per Mike's suggestion.

Re: [DFDL-WG]
How to parse an email address
Other option would be to put @ as separator
on sequence.. the sequence contains 2 elements of type string localPart
and domain

Or you can use dfdl:lengthKind 'pattern' and supply a dfdl:lengthPattern
for localPart that consumes all data up to but not including the @.
Note: Neither dfdl:lengthKind 'pattern' or dfdl:inputValueCalc are supported
by IBM DFDL yet - this will be addressed in the near future :)

If you want the infoset to contain dfdl-wg@ogf.org,
but also to contain localPart and domain, then you are putting the same
data into multiple
fields, which can only be accomplished using inputValueCalc.
I suggest parse the data into localPart and domain by using the @ as terminator
for localPart, and whatever the boundary is for the domain.
then have another element which you inputValueCalc which contains the concatenation
of those fields with an '@' in the middle.
I choose this way, parse the pieces, compute the concatenation of them,
versus the other way round because the expression for the inputValueCalc
will be dead simple in this case, and you will get an ordinary error of
'delimiter not found' if the @ is missing from the data.
Contrast if you had one field which contains the whole email address and
two calculated elements which take substrings of that. Now you have two
inputValueCalc's. And if the @ isn't there in the string, you'll get errors
evaluating expressions, not ordinary parsing, etc.

Suppose I want to model an email address:
dfdl-wg@ogf.org
It’s a sequence of a string, an a character (@), and a
string.
In the MBTK it might look like this:
The problem, of course, is that the parser will grab all
of “dfdl-wg@ogf.org”
instead of just “dfdl-wg”. Setting validation facets doesn’t help,
b/c validation happens after parsing. Setting @ as a separator or
terminator would work, but that doesn’t seem right either, as the @ is
part of the email address, and I would want to keep it in the infoset.
How do I think about this problem?
TIA
