DESCRIPTION

In XMetaL Author 6.0 we introduced “Support for modular XML documents via W3C XInclude”. Beyond the checkbox on the marketing datasheet, what does this support really mean for partners and customers? As an XMetaL implementer, you can provide your end users with new content reuse capabilities. We take a look at what XMetaL allows, and what you need to do to allow your end users to take advantage of this powerful new feature.
