Because XML is more of a metalanguage than a language itself, it is easy to create standards that seem complete enough for B2B communication. Eager to get their standards out there, lots of vendors developed so-called standards independent of one another. In this case, most vendors released their standards too soon, before they would be truly useful for businesses. But it will take years. But each of these standards is slightly different.
Different industries have different needs for transactions, hence different kinds of XML standards.
Loesgen believes that industry participants will come together to develop a standard.
