External consumers might reference to a specific section using the id
attribute - finding "unused" id
s seems to be impossible in this scenario, e.g.
<img src="https://example.com/sprites.svg#some-icon">
<svg><use href="https://example.com/sprites.svg#some-icon"></use></svg>
Cleaning out SVG elements that don't have any children might happen by introducing a new removeEmptyElements($flags)
, and flags e.g. being enum constants NO_ATTRS
, NO_CHILDREN
. In any way, I think consumers of this library should explicitly use this particular behavior, I would not make it part of the default processing.
definitely ; but this ID should be in the root line of or not within the content - or?
There are no restrictions to which nodes and how deep down in document hierarchy id
attributes are assigned.
