namespace StyleEx

[ISO/IEC 29500-1 1st Edition]

style (Style Definition)

This element specifies the definition of a single style within a WordprocessingML document. A style is a predefined set of table, numbering, paragraph, and/or character properties which can be applied to regions within a document.

The style definition for any style definition can be divided into three segments:

General style properties
Style type
Style type-specific properties

General style properties refers to the set of properties which can be used regardless of the style type; for example, the style name, additional aliases for the style, a style ID (used by the document content to refer to the style), if style is hidden, if style is locked, etc.

[Example: Consider a style called Heading a document as follows:

<w:style w:type="paragraph" w:styleId="Heading1">  
  <w:name w:val="Heading 1"/>  
  <w:basedOn w:val="Normal"/>  
  <w:next w:val="Normal"/>  
  <w:link w:val="Heading1Char"/>  
  <w:uiPriority w:val="1"/>  
  <w:qformat/>  
  <w:rsid w:val="00F303CE"/>  
  …</w:style>

Above the formatting information specific to this style type are a set of general style properties which define information shared by all style types. end example]

Style types refers to the property on a style which defines the type of style created with this style definition. WordprocessingML supports six types of style definitions by the values for the style definition's type attribute:

Paragraph styles
Character styles
Linked styles (paragraph + character) [Note: Accomplished via the link element (§17.7.4.6). end note]
Table styles
Numbering styles
Default paragraph + character properties

[Example: Consider a style called Heading a document as follows:

<w:style w:type="paragraph" w:styleId="Heading1">  
  <w:name w:val="heading 1"/>  
  <w:basedOn w:val="Normal"/>  
  <w:next w:val="Normal"/>  
  <w:link w:val="Heading1Char"/>  
  <w:uiPriority w:val="1"/>  
  <w:qformat/>  
  <w:rsid w:val="00F303CE"/>  
  …</w:style>

The type attribute has a value of paragraph, which indicates that the following style definition is a paragraph style. end example]

Style type-specific properties refers to the payload of the style: its formatting information as well as any properties which apply only to that style type.

[Example: Consider a table style with primary name Normal Table defined as follows:

<w:style w:type="table" w:default="1" w:styleId="TableNormal">  
  <w:name w:val="Normal Table"/>  
  …  <w:tblPr>  
    <w:tblInd w:w="0" w:type="dxa"/>  
    <w:tblCellMar>  
      <w:top w:w="0" w:type="dxa"/>  
      <w:left w:w="108" w:type="dxa"/>  
      <w:bottom w:w="0" w:type="dxa"/>  
      <w:right w:w="108" w:type="dxa"/>  
    </w:tblCellMar>  
  </w:tblPr>  
</w:style>

The tblPr element contains the formatting payload for this table style, which is only applicable to a table style. end example]
