Use of xrefs to topics
When content contains embedded xrefs, it creates a dependency on the topics that are the target of xrefs. If the content is localized, all content that is referenced is included in the package sent for translation. Therefore, if you are reusing content with xrefs to other topics, those other topics are included in the package for localization, even if only an element in that topic is being reused that does not include the xref. This increases the translation costs.
