DSML is the Directory Services Markup Language, an XML dialect for working with directory information. The DSML Tools provide for the querying of any LDAP directory (with search results output as DSML), the importing of DSML data into any LDAP directory, the directory-context validation of DSML (checking for illegal attributes in the entries, etc.), and the calculation of the differences (for a directory) between two DSML documents to provide an XML Diff algorithm for DSML data. This software makes all LDAP-supporting directories DSML-enabled. It can also check the integrity of DSML data, and show at a glance how two data sets, represented as DSML, differ.
DocBook is an XML vocabulary which enables you to create document content in a presentation-neutral form that captures the logical structure of the content. Using the DocBook Project XSL stylesheets, you can publish DocBook content as HTML pages and PDF files and other formats, including man pages, HTML Help, and JavaHelp.
sgml2x is a script designed to help applying a DSSSL stylesheet to an SGML or XML document. It has a couple of interesting features, such as multiple possible stylesheets per document class, easy integration of new stylesheets by adding a simple new definition file in a configuration directory (system-wide, per-user, or per-project), and automatic selection of a default stylesheet to be used. It is already set up for DocBook SGML/XML.
AlcoveBook DTD and stylesheets is a strict subset of the DocBook DTD. The ultimate goal is to provide a series of DTDs for enterprise use, commercial proposal, whitepaper, etc. For now, this is one single SGML DTD. The stylesheets are usable with both DocBook and AlcoveBook. They include a set of extensions over Norman Walsh's modular docbook stylesheets (docbook-dsssl), and a book- like layout for articles.
FleXML reads a DTD (Document Type Definition) describing the format of XML documents and produces a validating XML processor with an interface to support XML applications. Because the DTD is known in advance, the C code generated is much more efficient than equivalent code using an API such as SAX.
