* @brief The VDomDocument class working with pattern file.
* @brief The VDomDocument class represents a Valentina document (.val file).
*
* A Valentina document describes the construction of a sewing pattern. The
* information is stored in XML format. By parsing a VDomDocument, the contained
* pattern is rendered to a Valentina graphics scene (VMainGraphicsScene).
*
* A sewing pattern consists of increments (TODO: what are increments?) and one
* or more pattern pieces.
*
* A pattern piece contains
* 1) auxiliary pattern construction elements (calculation),
* 2) pattern construction elements (modeling), and
* 3) special markers, e.g. seam allowances (details).
* Of these, 2) and 3) are visible in the final pattern (draw mode 'Modeling'),
* 1) is only displayed when editing (draw mode 'Calculation') the pattern.
