Just checking - did we close on this? Regards Steve Hanson Architect, Data Format Description Language (DFDL) Co-Chair, OGF DFDL Working Group IBM SWG, Hursley, UK smh@uk.ibm.com tel:+44-1962-815848 ----- Forwarded by Steve Hanson/UK/IBM on 21/01/2013 18:38 ----- From: Mike Beckerle <mbeckerle.dfdl@gmail.com> To: Steve Hanson/UK/IBM@IBMGB, Cc: dfdl-wg@ogf.org Date: 19/11/2012 21:08 Subject: Re: [DFDL-WG] proposed clarification/narrowing - no twos-complement decimal, integer or nonNegativeInteger 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. Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
