Subject: RE: [tag] Requirement: component like a tag but for 'namespace'
Should we use another name than "@namespace" ? That could be confusing with the actual namespace of the TAG markup, which will of course be different. How about "idspace" or the like? -J -----Original Message----- From: stephen.green@systml.co.uk [mailto:stephen.green@systml.co.uk] Sent: Saturday, May 24, 2008 10:53 AM To: tag@lists.oasis-open.org Subject: RE: [tag] Requirement: component like a tag but for 'namespace' This is what a TA with such a namespace might look like <testAssertion id="TA-0001" enabled="true" namespace="urn:acme:small-widget:ta:1-0"> <tatag name="conformanceProfile">Basic</tatag> <tatag name="name2">string value</tatag> <description>This is a sample TA for the specification statement REQ-0001</description> <normsource> <reference>REQ-0001</reference> <quote>string</quote> <interpretation>string</interpretation> </normsource> <prescription level="mandatory"/> <target name="widget" exprlang="xpath2" id="relative XPath expression">absolute XPath expression</target> <prerequisite> <general>some plain-text condition, subject to possible stricter syntax</general> <precondition exprlang="extended-xpath2">(TA:1234='true' and TA:2355:relation='true') or (TA:4444='true' and [target predicate])</precondition> </prerequisite> <predicate exprlang="xpath2">relative XPath expression</predicate> </testAssertion> Expressed as model it might look like this TA_id: [namespace:urn:acme:small-widget:ta:1-0] TA-0001 TAG: name="conformanceProfile" value="Basic TAG: name="name2" value="string value" Description: This is a sample TA for the specification statement REQ-0001 Normative Source: REQ-0001 ... -- Stephen D.
