17.18.106 ST_TextScalePercent
This simple type specifies that the percentage by which the contents of a run shall be expanded or compressed with respect to its normal (100%) character width, with a minimum width of 1% and maximum width of 600%.
[Example: Consider a run of text that must be compressed by half when displaying each character within the contents of the run. This constraint is specified using the following WordprocessingML:
<w:rPr>
<w:w w:val="50%"/>
</w:rPr>
This run explicitly declares that the w value is 50%, so the contents of this run appear at 50% of their normal character width by compressing the width of each character. end example]
This simple type also
specifies the following restrictions:
This simple type’s contents shall match the following regular expression pattern: - 0*(600|([0-5]?[0-9]?[0-9]))%. [Note: The W3C XML Schema definition of this simple type’s content model (ST_TextScalePercent) is located in A.1. end note]
