A more complex example would be good where the link is at the group level. The 'a' element uses Xlink. For hyperlinks in SVG, only simple links are available. Because SVG content often represent a picture or drawing of something, a common need is to link into a particular view of the document, where a view indicates the initial transformations so as to present a closeup of a particular section of the document. To link into a particular view of an SVG document, the URI fragment identifier needs to be a correctly formed SVG fragment identifier .
Number is a real number.
The parameter values for viewBoxSpec corresponds to to the parameter values for the viewBox attribute on the 'svg' element. The parameter values for preserveAspectRatioSpec corresponds to to the parameter values for the preserveAspectRatio attribute on the 'svg' element. The parameter values for transformSpec corresponds to to the parameter values for the transform attribute that is available on many SVG elements. The parameter values for enableZoomAndPanControlsSpec corresponds to to the parameter values for the enableZoomAndPanControls attribute on the 'svg' element. The parameter values for viewTargetSpec corresponds to to the parameter values for the viewTarget attribute on the 'view' element.
