I believe the spec is a bit confusing when it comes to titles with markup for UI Preview.
The Compact representation has a dcterms:title property. It's defined as an XML Literal that can contain XHTML markup [1]. My understanding of XML Literals as discussed in the RDF Primer [2] means a title with markup would look like this, <dcterms:title>12345: <s>Null pointer exception during startup</s></dcterms:title> The example [3] of this resource has a title like this, however, <dcterms:title> 12345: <s>Null pointer exception during startup</s> </dcterms:title> The example doesn't seem to fit with the description. It's very difficult to parse the former using XPath. For instance, the expression "/oslc:Compact/dcterms:title" takes out the "<s>" and "</s>" Most implementations I'm aware also follow the example where markup is encoded. It means special characters need to be "double encoded." For instance, "12345: Values > 1000 incorrectly calculated" would be, <dcterms:title>12345: Values &gt; 1000 incorrectly calculated</dcterms:title> I think we should add more clarity to the spec here, as getting this wrong can open up consumers to cross-site scripting attacks. I'd also suggest we say that providers MUST NOT use any markup with a <script> tag and consumer MUST NOT display any markup with a <script> tag to guard against this problem.
