Description

DOM-based XML parsing and rendering.

In this module, attribute values and content nodes can contain either raw text or entities. In most cases, these can be fully resolved at parsing. If that is the case for your documents, the Text.XML module provides simplified datatypes that only contain raw text.

rsNamespaces :: RenderSettings -> [(Text, Text)] #

Defines some top level namespace definitions to be used, in the form of (prefix, namespace). This has absolutely no impact on the meaning of your documents, but can increase readability by moving commonly used namespace declarations to the top level.
