For attributes of block elements, you can do the following:
Assign block element attributes
Override block element attributes
Assign interpolated parent attributes
Override interpolated parent attributes
When you want to override default or assigned attributes, keep in mind:
Where to use DITAAttribute markers
Assign block element attributes
To apply attributes (other than id) to a block element (other than <xref>), assign attribute="value" pairs, separated by spaces, to the paragraph format(s) mapped to the element:
[DITAParaAttributes] ; para format (wildcards OK) = attributes ParaFmt = attribute1="value1" attribute2="value2" ...
You can use DITA2Go macros for any part of the assignment, or even for the entire assignment. For example:
[DITAParaAttributes] ParaFmt = <$MacroToWriteAttrs>
Override block element attributes
To override a setting in [DITAParaAttributes] or to override default attributes for a particular instance of a block element, place a DITAAttribute PI marker in a paragraph mapped to the element, with content as follows:
elementname: attribute1="value1" attribute2="value2" ...
linklist: role="friend" type="reference"
The name of the element must be followed by a colon. Separate attribute="value" pairs with a space. Each value must be enclosed in double quotes. You can use DITA2Go macros for everything after the colon.
Assign interpolated parent attributes
To assign attributes to an interpolated parent of a block element:
[DITAParentAttributes] ; para format (wildcards OK) = parentname: attributes ParaFmt = parentname: attribute1="value1" attribute2="value2" ...
You can use DITA2Go macros for the assignment.
Override interpolated parent attributes
To override a setting in [DITAParentAttributes] or to override default attributes for an interpolated parent of a block element, place a DITAAttribute PI marker in a paragraph mapped to the element, with content as follows:
parentname: attribute1="value1" attribute2="value2" ...
To apply attributes to more than one interpolated parent, use a separate marker for each parent.
Where to use DITAAttribute markers
Use DITAAttribute PI markers only to supply attribute values other than the DTD default values for an element, or to override attribute values specified in a configuration file. Do not use DITAAttribute PI markers for any of the following:
A DITAAttribute PI marker overrides settings in [DITAParaAttributes] and [DITAParentAttributes], but does not override settings in [DITACharAttributes] (see §24.4.6.5 Specifying attribute values for an inline element) or [DITATableAttributes] (see §24.6 Specifying options for tables in DITA XML).
