Related QuestionsWhy do you use a DTD instead of a schema?
MusicXML FAQ (Frequently Asked Questions)When we started developing MusicXML, a DTD (Document Type Definition) was the only official W3C recommendation for defining an XML document. Since that time, XML Schemas have become an official W3C recommendation, and alternative schema languages like RELAX NG have also become available. W3C XML Schemas offer many benefits when using XML in electronic commerce and business database applications. For musical documents, though, the advantages are less compelling.
Related QuestionsIs SBML a database schema?
SBML Frequently Asked QuestionsNot specifically. There is no reason why SBML models could not be stored in a database, nor is there any reason why you could not use SBML as a schema. However, this was not the motivation for creating SBML. An SBML model is meant to encode a consistent view of knowledge of a biological system. SBML is not meant to encode a large set of potentially conflicting knowledge about such a system.

JavaChina: FAQ on XML by Roseanne ZhangIMHO, no, xml schema will gain more market shares, but it will never replace DTD. Xml schema has a serious problem, which is too complicated. Read an excellent article from Dr. David Mertz here Comparing W3C XML Schemas and Document Type Definitions (DTDs).C (born in 1970's), C++ (born in 1980's), Java (born in 1990's) have not finally replaced FORTRAN/COBOL ((born in 1950's) yet. .NET ((born in the 21st century) is actually making FORTRAN/COBOL more alive than before.

products & atomik & overview & benefitsAtomik works with almost all DTDs and Schemas that conform to the XML standards defined by the World Wide Web Consortium (W3C). If your DTD or Schema uses external entity references, you will need to make sure these are available to Atomik Roundtrip as it is not possible for QuarkXPress to access these across the Web. Entity locations and other parameters can be defined in the Atomik Roundtrip preferences.
Related QuestionsPaul's Newbie XML FAQYou don't. Who said you did? Just make sure your XML is well formed, and then you can make sure it is valid inside your own source code application. And then, of course, you'll need to document your XML format for others who might want to use it. If, however, you want to lean on a schema to let the XML parser check its validity for you, and if you want to use the schema as a way of communicating your XML format to others, well, that's okay too.Related Questions
Can a database schema be created and modified by code?
Frequently asked questions about VistaDB database engine and...Yes. You may create and modify database schemas (i.e. structures) via code. Both SQL commands and DDA objects may be used. VistaDB 3 supports CLR Procs which let you store managed .NET source code (C#, VB.NET) in the database, thereby providing even more power and flexibility than Stored Procs. TSQL Stored Procs will be added in a later release (see roadmap).

Frequently Asked QuestionsThe overall structure of the database tables that store information: user profile data, content metadata, or pure structured information.

Related QuestionsWhat is a DTD? What is an XML Schema?
FAQ: What is the DDI?Tagging itself isn't useful unless certain rules are established. For example, if one investigator uses the tag <title> to denote a study title, while another uses <study-title> or <studyTitle>, then immediately the XML becomes less useful because there's no easy way for a computer application to determine where the title can be located. To prevent this situation, we make use of a Document Type Definition (DTD) or an XML Schema.

Related QuestionsWhat is the Schema?
Environment settings set by a batch file are not working.The Schema is a blueprint of all objects in the domain and when first created a default Schema exists which contains definitions for users, computers, domains etc. Because of this, you can only have one schema per domain as you cannot have multiple definitions of the same object. The default schema definition is defined in the SCHEMA.INI file that also contains the initial structure for the NTDS.DIT (storage for the Directory data). This file is located in the %systemroot%\ntds directory.

JavaChina: FAQ on XML by Roseanne ZhangThe answer is yes or no. XML spy or anyone else can make an example from xml schema or dtd easily. I also made 4 examples from my trivial DTD on my FAQ here. This does not mean you can generate XML deterministically from xml schema or dtd. If you make your algorithm a lot more complicated by using (direct) graph theory, you even can decide the root element. However, it is still non-deterministic.
