I agree that people might want a non-XML syntax for merely defining their Micro-markup but if there is going to be any validation in the Micro-parser I'd reckon they wouldn't want to go to the trouble of implementing two syntaxes (they will just have implemented MicroXML) - unless the schema syntax is incredibly simple or exists already (like JSON perhaps :-) I did some more rough work on a reduced 'XSD-like' language (defined using its own schema language) which could probably be mapped to XSD, to compact relaxN, etc <schema name="MicroSchema-draft" version="draft2"> <element name="schema"> <group> <element ref="element" maxOccurs="unbounded" /> <element ref="group" maxOccurs="unbounded" > </group> <attribute name="name" type="string" /> <attribute name="version" type="string" /> </element> <element name="element"> <group maxOccurs="unbounded"> <element ref="element" /> <element ref="group" /> </group> <attribute name="ref" type="string" /> <attribute name="name" type="string" /> <attribute name="type" type="string"> <!-- enumeration = string | integer | decimal | date | sequence --> </attribute> </element> <element name="attribute"> <attribute name="ref" type="string" /> <attribute name="name" type="string" /> <attribute name="type" type="string"> <!-- enumeration = string | integer | decimal | date | sequence --> </attribute> </element> </schema> ---- Stephen D Green On 17 December 2010 18:42, Costello, Roger L. <costello@mitre.org> wrote: > Hi Folks, > > A validation language for Micro XML ... is XML syntax necessary for the validation language? > > To avoid bias, perhaps rather than "Micro XSD" the language should be referred to simply as a validation language for Micro XML, e.g., Micro VL. > > When is XML syntax needed and useful?
