#### 17.4.5.1 Specifying attribute values for a block element or ancestor

You can do any of the following for block elements:

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 DocBook Attribute 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:

[DocBookParaAttributes]

; Frame para format (wildcards OK) = attributes

ParaFmt = attribute1="value1" attribute2="value2" ...

You can use Mif2Go macros for any part of the assignment, or even for the entire assignment. For example:

[DocBookParaAttributes]

ParaFmt = <$WriteAttrMacro>

Override block element attributes

To override a setting in [DocBookParaAttributes] or to override default attributes for a particular instance of a block element, place a DocBookAttribute marker in a paragraph mapped to the element, with content as follows:

elementname: attribute1="value1" attribute2="value2" ...

For example:

step: performance="optional"

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 Mif2Go macros for everything after the colon.

Assign interpolated parent attributes

To assign attributes to an interpolated parent of a block element:

[DocBookParentAttributes]

; Frame para format (wildcards OK) = parentname: attributes

ParaFmt = parentname: attribute1="value1" attribute2="value2" ...

You can use Mif2Go macros for the assignment.

Override interpolated parent attributes

To override a setting in [DocBookParentAttributes] or to override default attributes for an interpolated parent of a block element, place a DocBookAttribute 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 DocBook Attribute marker s

Use DocBookAttribute 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 DocBookAttribute markers for either of the following:

• The id attribute of the current element; use a DocBookElemID marker instead. See §17.4.4.4 Specifying an ID for an individual block element or parent.

• The id attribute of an interpolated parent of the current element; use a DocBookParentID marker instead. See §17.4.4.4 Specifying an ID for an individual block element or parent.

A DocBookAttribute marker overrides settings in [DocBookParaAttributes] and [DocBookParentAttributes], but does not override settings in [DocBookCharAttributes] (see §17.4.5.2 Specifying attribute values for an inline element).
