Chapter 3 . Extensions to the XProc 3.0 standard
MorganaXProc-III's implementation of XProc 3.0 has the following non standard features:
1 . Serialization options
MorganaXProc-III implements the following serialization
options: mox:indent-spaces and
mox:indent-arrays.
1.1 . Serialization parameter 'mox:indent-spaces'
With output methods XML, HTML, and XHTML and 'indent' :
true(), the 'mox:indent-spaces' key can be used
to control the amount of indentation. The key must be associated with an
instance of xs:integer. The setting is ignored, if the
integer value if less than 1. The default value for indentation is 3.
This feature can be used in any serialization map in XProc
as well as with a map as second parameter in
fn:serialization#2.
1.2 . Serialization parameter 'mox:indent-arrays'
When serializing JSON documents with indent : true(),
parameter 'mox:indent-arrays' can be used to control whether
JSON arrays are indented or not. The default value is true(),
but with setting the parameter to false() indentation of
arrays is suppressed.
