# Creating filters

To set up a new filter, create an XML document using the schema ‘filter.xsd’.

Filters consist of a title, optional lists of excluded and inherited filters, and a list of elements. Each element specifies a particular tag and, optionally, a map of attribute keys and values.

Here is a sample filter definition:

    <?xml version="1.0" encoding="UTF-8"?>
    <filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:noNamespaceSchemaLocation="filter.xsd">
      <title>WordprocessingML</title>
      <element>urn:schemas-microsoft-com:office:office:DocumentProperties</element>
      <element>urn:schemas-microsoft-com:office:office:CustomDocumentProperties</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:binData</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:delText</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:docPr</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:fldData</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:fonts</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:instrText</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:lists</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:shapeDefaults</element>
      <element>http://schemas.microsoft.com/office/word/2003/wordml:styles</element>
    </filter>

Filter processing is namespace aware (hence the long element names).
