[jira] [Commented] (XERCESJ-1518) Forward references to types etc are not subject to whitespace normalization.

["Chris Simmons (JIRA)" <xe...@xml.apache.org>]

    [ https://issues.apache.org/jira/browse/XERCESJ-1518?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13066856#comment-13066856 ] 

Chris Simmons commented on XERCESJ-1518:
----------------------------------------

Whilst the patch fixes the observed problem I doubt that its complete as anything using the attribute name value directly is liable to be similarly wrong so they all need review.  Perhaps the correct fix is to refactor everything using the SchemaSymbols.ATT_NAME to instead use the appropriate validator (presumably the names are all of type xs:NCName) to construct an object to use as a key instead.  I think that this is effectively what happens when there's a backwards reference.

> If, say, an element references its type and the element is lexically before the type then the type may fail to resolve if the type name contains whitespace.  This will happen for all cross references as they are handled similarly.  I'll attach a patch with a test and simple fix shortly.
