The length of this element should be more than 1 character
by Garriss Jr., James P. 06 Apr '13

06 Apr '13

Suppose I have a text element whose length must be greater than 1 character. I think an assert should be able to handle this, and there's a string-length() function, so I wrote this for my xPath expression: fn:string-length(.) > 1 But MBTK is telling me: CTDX1100E : XSD: The attribute 'null' is not permitted (This is, BTW, a less-than-helpful error message.) [cid:image001.png@01CE3200.633AA6A0] I added it manually, like so: <xsd:element name="Body" type="xsd:string"> <xsd:annotation> <xsd:appinfo source="http://www.ogf.org/dfdl/"> <dfdl:assert message="The length of the body must be more than 1 character"> { fn:string-length(.) > 1 } </dfdl:assert> </xsd:appinfo> </xsd:annotation> </xsd:element> And MBTK gave me this error: CTDV1493E : XPath expression '{ fn:string-length(.) > 1 }' contains a path expression that does not resolve to an element in the schema: 'Found ">" at line 1, column 23. Expected one of "}" "or" "and" "*" "div" "idiv" "mod" "eq" "ne" "lt" "le" "gt" "ge" "[" "-" "+" "/"'. Element: #xmlns(p="http://fileid")xscd(/schemaElement::p:ImfMime/type::0/model::sequence/schemaElement::Body). So this indicates it doesn't like the ">" character. So I changed it to > but got the same message. So am I implementing this wrong? Or does MBTK not support this function? Daffodil is also giving me an error: Schema Definition Error: XPath Compilation Error: net.sf.saxon.trans.XPathException: XPath syntax error at char 20 in {fn:string-length(.) > 1}: Prefix fn has not been declared Schema context: element.Body. Location in file:/C:/Users/jgarriss/daffodil-0.8.1/bin/DetectImfMime.xsd But this is a different issue, a namespace issue. MBTK magically knows about the "fn:" namespace, but Daffodil doesn't. It's not declared in the root element: <?xml version="1.0" encoding="UTF-8"?> <xsd:schema targetNamespace="http://fileid" xmlns:dfdl="http://www.ogf.org/dfdl/dfdl-1.0/" xmlns:fmt="http://www.ibm.com/dfdl/GeneralPurposeFormat" xmlns:ibmSchExtn="http://www.ibm.com/schema/extensions" xmlns:ns0="http://fileid" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> Help!

IMF Comments
by Garriss Jr., James P. 02 Apr '13

02 Apr '13

Comments can appear anywhere in the value of an email header. The initiator is an open paren, and the terminator a closed paren. They are meant only for human readers, thus they can be safely ignored by processors. These are equivalent: MIME-Version: 1.0 MIME-Version: 1.0 (produced by MetaSend Vx.x) MIME-Version: (produced by MetaSend Vx.x) 1.0 MIME-Version: 1.(produced by MetaSend Vx.x)0 I don't see comments used in too many headers, but they are used frequently in the Received header: Received: from e06smtp13.uk.ibm.com (e06smtp13.uk.ibm.com [195.75.94.109]) by smtpksrv1.mitre.org (Postfix) with ESMTP id 655301F069B for <jgarriss(a)mitre.org>; Tue, 12 Mar 2013 08:02:00 -0400 (EDT) How would you handle this in DFDL? Does it have a mechanism for saying, "This element can appear anywhere and any number of times inside of this other element?"

case insensitivity
by Garriss Jr., James P. 02 Apr '13

02 Apr '13

In IMF, headers are generally case insensitive. Thus these are equivalent: Content-Type: text/html Content-Type: TEXT/HTML Content-Type: Text/Html Content-Type: tExT/hTmL Does DFDL have a way to tell the parser to parse text in a case-insensitive manner? A quick search of the spec didn't reveal anything.

Encoded Words: A Problem for DFDL
by Garriss Jr., James P. 30 Mar '13

30 Mar '13

The attached PDF file details a feature of email headers known as encoded words. I think DFDL is incapable of modeling this feature, but I'd like to get your feedback. TIA
