function SVG.desc { <# .Synopsis Creates SVG desc elements .Description The **`<desc>`** element provides an accessible, long-text description of any SVG [container element](https://developer.mozilla.org/en-US/docs/Web/SVG/Element#container_elements) or [graphics element](https://developer.mozilla.org/en-US/docs/Web/SVG/Element#graphics_elements). Text in a `<desc>` element is not rendered as part of the graphic. If the element can be described by visible text, it is possible to reference that text with the [`aria-describedby`](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-describedby) attribute. If `aria-describedby` is used, it will take precedence over `<desc>`. The hidden text of a `<desc>` element can also be concatenated with the visible text of other elements using multiple IDs in an `aria-describedby` value. In that case, the `<desc>` element must provide an ID for reference. .Link https://pssvg.start-automating.com/SVG.desc .Link https://developer.mozilla.org/en-US/web/svg/element/desc/ .Link Write-SVG #> [Reflection.AssemblyMetadata('SVG.ElementName', 'desc')] [CmdletBinding(PositionalBinding=$false)] param( # The Contents of the desc element [Parameter(Position=0,ValueFromPipelineByPropertyName)] [Alias('InputObject','Text', 'InnerText', 'Contents')] $Content, # A dictionary containing data.
