17.13.8 Spelling and Grammar
The remaining kind of annotation stored in a WordprocessingML document, spelling and grammar errors are annotations used to specify the locations of existing spelling and grammatical errors within the contents of a document.
[Rationale: When a WordprocessingML document is saved, applications can choose to save currently flagged spelling and grammar errors, for two reasons:
- In order to increase the performance subsequent loads of the document (as those load operations can
- rely on the persisted proofing state of the document)
- In order to store words which must not be marked as proofing errors regardless of how they would
- normally be flagged by the proofing tools engine (i.e. to store spelling and grammar exceptions).
end rationale]
[Example: Consider the following paragraph consisting of two misspelled words, where the second word has been explicitly flagged as not being a spelling error. This paragraph would consist of the following WordprocessingML markup:
<w:p>
<w:proofErr w:type="spellStart"/>
<w:r>
<w:t>erqwt</w:t>
</w:r>
<w:proofErr w:type="spellEnd"/>
<w:r>
<w:t xml:space="preserve"> werewr</w:t>
</w:r>
</w:p>The proofErr elements, with a val attribute value of spellStart and spellEnd respectively, delimit the start and end the content in this paragraph which is stored as a spelling error. Since the second word is not included in that range, it is not stored as a spelling error. end example]
