Just reactivating this old stale thread. I don't see any language about this in the current draft I am working on which has all the v12 errata in it. Do we think this is needed? If so an action item to create the language is needed. ---------- Forwarded message ---------- From: Mike Beckerle <mbeckerle.dfdl@gmail.com> Date: Tue, Jan 22, 2013 at 11:06 AM Subject: Re: [DFDL-WG] Implementation limits To: Steve Hanson <smh@uk.ibm.com> Cc: dfdl-wg@ogf.org There is a section in the material about error types/kinds on implementation limit errors. It gives examples of implementation limits that might exist in different implementations. Today we found another interesting one: regex match time limit. ...mike On Mon, Jan 21, 2013 at 1:43 PM, Steve Hanson <smh@uk.ibm.com> wrote:
Just checking - did we close on this?

Do we have a section where this goes?
There are lots of implied implementation limits.
Maximum string length? Maximum hexbinary length? Maximum number of packed digits in various numbers.
Maximum length of a delimiter? Maximum length of a fixed attribute? Maximum length of a pattern regex expression? Maximum length of a regular expression?
There's also limits on buffering of data for unparsing, etc.
There's also limits on lookahead/speculation. I.e., how far an implementation is willing to speculate forward.
etc.
For some types these are clear: e.g., binary xs:int is 32 bits max.
Do we need a numbered section on implementation specific limits.
