self closing span "text-decoration:line-through", which is illegal, is showing up in structureDefinition resource.text.div narrative

[JohnMoehrke]

A tag is not allowed to be self-closing. Browsers tend to render it as if the span is not self-closed, and have indeterminant behavior around auto closing. https://stackoverflow.com/questions/2816833/can-a-span-be-closed-using-span

Note that the .html files do not have the same problem. Thus the conversion to/from the text.div seems to correct it. --- NOTE that a few months ago the .html files did have the problem, so some fix was made, but didn't fix the .text.div.

Typically this is found when a structureDefinition sets a cardinality (e.g. 0..0)

Low priority because the .html files are okay.

@JohnMoehrke Can you provide a specific example of what you're seeing that needs to be fixed. (Or at least point to a specific example where problematic narrative exists.)

[JohnMoehrke]

for example
https://profiles.ihe.net/ITI/PDQm/StructureDefinition-IHE.PDQm.Patient.json

has

...
<span style=\"text-decoration:line-through\">implicitRules</span><a name=\"Patient.implicitRules\"> </a></td><td style=\"vertical-align: top; text-align : left; background-color: #F7F7F7; border: 0px #F0F0F0 solid; padding:0px 4px 0px 4px\" class=\"hierarchy\"/><td style=\"vertical-align: top; text-align : left; background-color: #F7F7F7; border: 0px #F0F0F0 solid; padding:0px 4px 0px 4px\" class=\"hierarchy\"><span style=\"text-decoration:line-through\"/><span style=\"text-decoration:line-through\">0</span><span style=\"text-decoration:line-through\">..</span><span style=\"text-decoration:line-through\">0</span>
...

where most span setting line-through are properly closed, except ONE

<span style="text-decoration:line-through"/>

which is self closing.

[JohnMoehrke]

note that the above artifact in the .html has proper close

 <span style="text-decoration:line-through"></span>

although this is a very useless span.. it is at least not wrong.

[lmckenzi]

We should either not create the span or should trim empty spans.
