1.1. Additional or alternative `addon/` directories

Additional or alternative addon/ directories may be specified by the means of the XXE_ADDON_PATH environment variable.

If the XXE_ADDON_PATH environment variable is set to a non empty string, the content of this variable must be a list of directory names separated by character ";" (even on Unix). All the directories referenced in this list are recursively scanned by the XXE desktop application during its startup.

File names and "file://" URLs are both supported. Windows example:

C> set XXE_ADDON_PATH=C:\xxe\doc\configure\samples\example1;\
file:///C:/xxe/doc/configure/samples/example2

If this path ends with ";+", XXE_install_dir/addon/ is also scanned at startup time. Otherwise, this system directory, containing a large number of add-ons (DITA configuration, DocBook configuration, spell-checker, etc), is completely ignored.

Form @absolute URL is also supported.

Absolute URL specifies the location of a text file containing a list of (generally relative) URLs to be scanned by XXE. The URLs in this list are separated by white space.

Example, sample_configs.list:

example1
example1/example1.css
example1/example1.dtd
example1/example1.xml
example1/example1.xxe
example1/example1_catalog.xml
example2
example2/example2.css
example2/example2.xml
example2/example2.xsd
example2/example2.xxe
example2/example2_catalog.xml

Unix example:

$ export XXE_ADDON_PATH="@http://www.foo.com/xxe/sample_configs.list;+"
