Implementation dependent features

Chunking

Supported chunking methods:

select-topic
select-document
select-branch
by-topic
by-document
to-content
to-navigation.

When no chunk attribute values are given, no chunking is performed.

Note: In effect, for HTML based transformation types this is equivalent to select-document and by-document defaults.

Error recovery:

When two tokens from the same category are used, no error or warning is thrown.
When an unrecognized chunking method is used, no error or warning is thrown.

Filtering

Error recovery:

When there are multiple revprop elements with the same val attribute, no error or warning is thrown
When multiple prop elements define a duplicate attribute and value combination, attribute default, or fall-back behaviour, DOTJ007E error is thrown.

Debug attributes

The debug attributes are populated as follows:

xtrf

absolute system path of the source document

xtrc

element counter that uses the format

element-name ":" integer-counter ";" line-number ":" column-number

Image scaling

If both height and width attributes are given, image is scaled non-uniformly.

If scale attribute is not an unsigned integer, no error or warning is thrown during preprocessing.

Map processing

When a topicref element that references a map contains child topicref elements, DOTX068W error is thrown and the child topicref elements are ignored.

Link processing

When the value of href attribute is not a valid URI reference, DOTJ054E error is thrown. Depending on error recover mode, error recover may be attempted.

Copy-to processing

When the copy-to attribute is specified on a topicref, the content of the shortdesc element is not used to override the short description of the topic.
